摘要： Water is fed into the fuel cell stack in the hydrogen reactant stream. Some of the water is evaporated in the cells to cool the stack, and some of the water migrates through the stack from cell to cell. The water migration is the result of the water being dragged from the anode to the cathode through the electrolyte membrane and by the use of porous hydrophilic separator plates being interposed between adjacent cells in the stack. Water is forced through these porous separator plates by means of a reactant pressure differential maintained between the cathode and anode. The anode support plates provide a large surface area from which water is evaporated to perform the cooling function.

摘要： A molten carbonate fuel cell matrix material is described made up of a matrix tape portion and a bubble barrier portion. The matrix tape portion comprises particles inert to molten carbonate electrolyte, ceramic particles and a polymeric binder, the matrix tape being flexible, pliable and having rubber-like compliance at room temperature. The bubble barrier is a solid material having fine porosity up to about 50% by volume, optionally being bonded to the matrix tape. In operation in a fuel cell, the polymer binder burns off leaving the matrix and bubble barrier providing superior sealing, stability and performance properties to the fuel cell stack.

摘要： The medium (9), such as water, of a container (10), such as a fuel cell accumulator, is kept above freezing by a hydrogen/oxygen catalytic combustor (13) fed hydrogen from a source comprising a mechanical thermostatic valve (25) in thermal communication (26) with the container (10) and connected to a hydrogen supply (28). The combustor may comprise an ejector (32) having hydrogen through its primary inlet (31) drawing air through a secondary inlet (33). The combustor may comprise a diffusion combustor having a catalyst (38) spaced from a heating surface (30) and a diffusion control plate (40) low partial pressure of oxygen at the catalyst causing diffusion through the barrier. Water vapor from combustion condenses on a surface (146) and is led by hydrophilic woven carbon paper (126) to wicking material (133), which has smaller pores than the carbon paper, which leads the water downwardly, through a disk (140) and plugs (147) to atmospheric air. The noble metal catalyst mixture includes TEFLON® to permit water generated by combustion to flow by gravity out of the catalyst.

摘要： A procedure for starting up a fuel cell system that is disconnected from its primary load and has both its cathode and anode flow fields filled with air includes initiating a flow of air through the cathode flow field and rapidly displacing the air in the anode flow field by delivering a flow of fresh hydrogen containing fuel into the anode flow field, and thereafter connecting the primary load across the cell. Sufficiently fast purging of the anode flow field with hydrogen prior to connecting the cells to the load eliminates the need for purging the anode flow field with an inert gas, such as nitrogen, upon start-up.

摘要： A procedure for shutting down an operating fuel cell system that recirculates a portion of the anode exhaust in a recycle loop, includes disconnecting the primary load from the external circuit, stopping the flow of air to the cathode, and applying an auxiliary resistive load across the cells to reduce and/or limit cell voltage and reduce the cathode potential while fuel is still flowing to the anode and the anode exhaust is recirculating. The fuel flow is then stopped, but the anode exhaust continues to be circulated in the recycle loop to bring the hydrogen therein into contact with a catalyst in the presence of oxygen to convert the hydrogen to water, such as in a catalytic burner. The recirculating is continued until substantially all the hydrogen is removed. The cell may then be completely shut down. No inert gas purge is required as part of the shut-down process.
