A thermal management system for cooling electronic devices includes an immersion cooling system, a vapor buffer tank, and a liquid buffer tank. The immersion cooling system includes an immersion tank defining an immersion chamber, a working fluid in the immersion chamber, and a condenser. A liquid portion of the working fluid defines an immersion bath in the immersion chamber and a vapor portion defines a headspace above the immersion bath in the immersion chamber. The condenser condenses the vapor portion of the working fluid to the liquid portion of the working fluid. The vapor buffer tank is in fluid communication with the headspace, and a vapor valve selectively allows fluid communication between the vapor buffer tank and the headspace. The liquid buffer tank is in fluid communication with the immersion chamber, and a liquid valve selectively allows fluid communication between the liquid buffer tank and the immersion chamber.

The disclosed technology is generally directed to fuel cells. In one example of the technology, a fuel cell stack that includes an anode and a cathode causes a load to be driven. A control subsystem is measures at least one characteristic associated with the load, and to provide at least one control signal based, at least in part, on the at least one characteristic. An oxidizing agent input subsystem provides an oxidizing agent to the cathode of the fuel cell stack. A fuel input subsystem provides gaseous fuel to the anode of the fuel cell stack. The fuel input subsystem includes a fuel pump that is arranged to pump the gaseous fuel into the fuel input subsystem. A fuel-side high-speed valve adjusts mass flow of the gaseous fuel to the cathode of the fuel cell stack based on at least a first control signal of the at least one control signal.

Examples described in this disclosure relate to waste cold recuperation in fuel cell based power generation systems for datacenters. An example waste cold recuperation system includes a liquefied gas storage for supplying liquefied gas as a coolant to cool a first set of compute resources configurable to operate in a first cryogenic environment. The system is configurable to supply at least some of the vapor phase of the liquefied gas as a coolant to cool a second set of compute resources configurable to operate in a second cryogenic environment, resulting in the at least some of the vapor phase of the liquefied gas becoming a super-heated vapor phase of the liquefied gas. The system is configurable to supply the super-heated vapor phase of the liquefied gas as fuel to fuel cells for providing electrical power to a datacenter load including compute resources configurable to operate in a non-cryogenic environment.

A processing unit includes a first die and a second die with a microfluidic volume between the first die and the second die. At least one heat transfer structure couples the first die to the second die and is located in the microfluid volume. An electrochemical fluid is positioned in the microfluidic volume to provide electrochemical energy to at least one of the first die and the second die and receive heat from the first die and the second die.

Techniques of deploying fuel cells in a facility are described herein. In one embodiment, a method includes identifying a location of the receptacle at the facility that the fuel cell is connected upon detecting the fuel connector of the second side of the carrier being coupled to a fuel port at a receptacle at the facility. The method can then include generating and storing, in a database, a fuel cell record indicating that the fuel cell is physically connected to the receptacle at the identified location in the facility and instructing a control device in the facility corresponding to the identified location to provide fuel to the fuel cell via the fuel port, the fuel connector, the connection between the first side and the second side of the carrier, and the fuel inlet of the fuel cell.

Fuel cell deployment systems and apparatus

Cooling a first device and second device in a fashion to produce water. The method includes collecting environmental air from an environment. The environmental air is used to cool a first device. Cooling the first device generates first device exhaust air produced from the environmental air. The first device exhaust air is provided to a first device portion of a heat exchanger. At a second device portion of the heat exchanger, thermally coupled to the first device portion of the heat exchanger, second device exhaust air generated by cooling a second device is received. At the heat exchanger, the first device exhaust air is used to cool the second device exhaust air to a dew point, causing condensed water to be created from the second device exhaust air. The condensed water is collected.

Fuel cell systems configured for efficient byproduct recovery and reuse are disclosed herein. In one embodiment, a fuel cell system includes a reformer configured to reform a fuel containing methane (CH) with steam to produce a reformed fuel having methane (CH), carbon monoxide (CO), and hydrogen (H). The fuel cell system also includes a fuel cell configured to perform an electrochemical reaction between a first portion of the reformed fuel and oxygen (O) to produce electricity and an exhaust having carbon dioxide (CO), water (HO), and a second portion of the reformed fuel. The fuel cell system further includes an oxygen enricher configured to generate an oxygen enriched gas and a combustion chamber configured to combust the second portion of the reformed fuel with the oxygen enriched gas.

Efficient byproduct harvesting from fuel cells

Improving the operations of a computer system that is located within a power grid and that is associated with its own power sources. Past operational characteristics of the power grid are analyzed to derive learned characteristics for the power grid. Future operational characteristics of the power grid are also monitored. A prediction regarding a future load event associated with the power grid is then generated using the learned characteristics and the monitored characteristics. In response to this prediction, one or more operations are performed to balance the computer system with the power grid during the future load event, and to ensure a determined availability of services associated with the computer system during the future load event.

Learning power grid characteristics to anticipate load

This document relates to electricity management using modulated waveforms. One example modulates electricity to obtain modulated electricity having at least two different alternating current frequencies including a first alternating current frequency and a second alternating current frequency. The example delivers the modulated electrical power having the at least two different alternating current frequencies to multiple different electrical devices, including a first electrical device configured to utilize the first alternating current frequency and a second electrical device configured to utilize the second alternating current frequency. The modulated electricity can be delivered at least partly over an electrical line shared by the first electrical device and the second electrical device.

Electricity management using modulated waveforms

Waste heat generated by devices as a byproduct of their operation is utilized to increase and maintain the temperature of non-potable water to neutralize biological contaminants, thereby rendering such water potable. The potable water can then be utilized for evaporative cooling of the devices. A temperature sensor monitors the temperature of the non-potable water and a controller controls the pump to provide sufficient time for the water to remain in the heat exchanger above a predetermined temperature to neutralize biological contaminants and render such water potable. To the extent that different devices generate different quantities and intensities of waste heat, multiple heat exchangers are utilized, with lower intensity waste heat serving to preheat the water and, thereby, reduce the amount of time needed to reach the target temperature in a primary heat exchanger. Waste heat not utilized to generate potable water can be utilized for other heat-driven processes.
