A high-temperature pressure sensor includes a pressure sensor device and a heater shell body external to the pressure sensor device for providing heat to the pressure sensor device. A particle-generating insulation material is encapsulated within an encapsulation material to form an encapsulated insulation structure comprising the particle-generating insulation material within the encapsulation material, such that the encapsulation material substantially contains particles generated by the particle-generating insulation material within encapsulated insulation structure. The encapsulated insulation structure is disposed adjacent to an exterior of the heater shell body.

Apparatus and method for thermal insulation of high-temperature pressure sensors

A fuel cell system for providing power to a load, and having a safety mode, is disclosed. The system includes a fuel cell configured to convert fuel to electrical power and coupled so as to provide electrical power at a fuel cell power output, a system power port having a power connection and a data connection, configured to be reversibly coupled to the load, a power connection controller, coupled to the fuel cell power output and to the system power port, and configured to enable and disable the power connection, and a fuel cell system controller coupled to the fuel cell, the data connection and the power connection controller. The fuel cell system controller has a normal mode and a safety mode. A user selection determines whether the fuel cell system controller is in the normal mode or the safety mode. If the load has a smart power port, the data connection is configured to communicate over the smart power port. In the normal mode, the fuel cell system controller is configured to enable the power connection independent of the data connection. In the safety mode, the fuel cell system controller is configured to enable the power connection only when an approved communication is received over the data connection from the load. A related method for operating the fuel cell system is also disclosed.

Fuel cell system having a safety mode

A fuel cell system having an air quality sensor suite includes a fuel cell having an anode and a cathode, a fuel source providing a fuel flow, a fuel flow rate sensor having a fuel flow rate sensor output, a fuel flow control device, a fuel oxidizer flow conduit, a first mixing region coupled to the fuel source and the fuel oxidizer flow conduit, an anode chamber coupled to the anode, a combustion oxidizer flow conduit, a second mixing region coupled to the combustion oxidizer flow conduit, and at least one oxidizer flow rate sensor having an oxidizer flow rate sensor output. The system further includes at least one oxidizer pump, an air quality sensor having an air quality sensor output, and a control system coupled to the fuel flow rate sensor output, the oxidizer flow rate sensor output, and the air quality sensor output.

Fuel cell system having an air quality sensor suite

Fuel cells having an efficient means of thermal insulation such that all of the components requiring high temperature operation are contained within a single housing and whereby such thermal insulation is disposed exterior to such housing.
