A flexible fuel cell power system comprising one or more fuel cell cartridges (which contain fuel cell modules) connected to a fuel cell system is provided. The components of the flexible fuel cell power system may be placed on a shared backbone with flexible joints, and may be made of flexible materials so that the entire system can be worn by a human being.

Flexible fuel cell power system

This disclosure is drawn to systems, devices, apparatuses, and/or methods, related to fuel cell cartridges. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to compact fuel cell cartridges for producing hydrogen gas for use by fuel cells. Some example fuel cell cartridges may include a reactor module for storing a reactant, a water module for storing water, and an interface coupling the reactor module and the water module. The interface may permit the water to flow from the water module to the reactor module such that the water mixes with the reactant in the reactor module to form a gas (e.g., hydrogen gas) that may exit through a gas outlet.

Fuel cell cartridge

Systems, devices, and methods combine thermally stable reactant materials and aqueous solutions to generate hydrogen and a non-toxic liquid by-product. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Springs and other pressurization mechanisms pressurize and deliver an aqueous solution to the reaction. A check valve and other pressure regulation mechanisms regulate the pressure of the aqueous solution delivered to the reactant fuel material in the reactor based upon characteristics of the pressurization mechanisms and can regulate the pressure of the delivered aqueous solution as a steady decay associated with the pressurization force. The pressure regulation mechanism can also prevent hydrogen gas from deflecting the pressure regulation mechanism.

Hydrogen generation systems and methods utilizing sodium silicide and sodium silica gel materials

Systems, devices, and methods combine reactant materials and aqueous solutions to generate hydrogen. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Multiple inlets of varied placement geometries deliver aqueous solution to the reaction. The reactant materials and aqueous solution are churned to control the state of the reaction. The aqueous solution can be recycled and returned to the reaction. One system operates over a range of temperatures and pressures and includes a hydrogen separator, a heat removal mechanism, and state of reaction control devices. The systems, devices, and methods of generating hydrogen provide thermally stable solids, near-instant reaction with the aqueous solutions, and a non-toxic liquid by-product.

Hydrogen generation systems utilizing sodium silicide and sodium silica gel materials

A water reactive hydrogen generation system includes devices and methods to combine reactant fuel materials and aqueous solutions to generate hydrogen. The generated hydrogen is used in a fuel cell or other application. The water reactive hydrogen generation system includes a reactant fuel chamber, a reactor chamber (zone), a water solution inlet, a hydrogen output port, and a material delivery device. The material delivery device can include a drive screw and a sliding piston to move the fuel material into the reactor zone when a reaction is initiated. As the reaction takes place, the reaction waste product is removed from the reaction zone to allow additional reactant fuel materials and aqueous solutions to be introduced and to continue the hydrogen-generating reaction. A reaction waste product created is exchanged for additional reactant fuel material at determined intervals to allow the reaction to continue until the reactant fuel is exhausted.

Water reactive hydrogen generation system and method with separation of waste products from water reactive materials

A water reactive hydrogen fueled power system includes devices and methods to combine reactant fuel materials and aqueous solutions to generate hydrogen. The generated hydrogen is converted in a fuel cell to provide electricity. The water reactive hydrogen fueled power system includes a fuel cell, a water feed tray, and a fuel cartridge to generate power for portable power electronics. The removable fuel cartridge is encompassed by the water feed tray and fuel cell. The water feed tray is refillable with water by a user. The water is then transferred from the water feed tray into the fuel cartridge to generate hydrogen for the fuel cell which then produces power for the user.
