A fuel cell assembly comprises a separating structure configured for separating a first reactant and a second reactant wherein the separating structure has an opening therein. The fuel cell assembly further comprises a fuel cell comprising a first electrode, a second electrode, and an electrolyte interposed between the first and second electrodes, and a passage configured to introduce the second reactant to the second electrode. The electrolyte is bonded to the separating structure with the first electrode being situated within the opening, and the second electrode being situated within the passage.

Fuel cell system with separating structure bonded to electrolyte

A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustor gases in a hybrid fuel cell system combustor using a nozzle or plurality of nozzles to inject water or water vapor, downstream or directly into the combustor. A variable speed pump, actuated valve or other flow metering device regulates the supply of water to the nozzles and a steam generator. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.

High temperature protection of hybrid fuel cell system combustor and other components VIA water or water vapor injection

A system and method are disclosed for high temperature protection of combustor and other components by controlling the temperature of combustion chamber gases in a fuel cell system tail gas burner using a nozzle or plurality of nozzles to inject water or water vapor upstream, downstream or directly into the combustion chamber. A variable speed pump, actuated valve or other flow metering device regulates the supply of water or water vapor to the nozzles. For the case of water vapor, an evaporator is required between the pump and nozzles. Flow regulation is effected by a control algorithm that reacts to combustor temperature, changes in the power production of the fuel cell system and/or other related system parameters.
