摘要： A fuel cell power plant (10) having a fuel concentration sensor cell (54) is disclosed for detecting a concentration of fuel in a fuel cell (12) of the plant (10). A portion of a fuel exhaust stream is directed to flow through the sensor cell (54) adjacent to a membrane electrode assembly (60) of the sensor cell (54). A power circuit (62) may or may not deliver an electrical current to the cell (12), while changes in voltage across the cell (12) that are proportional to changes in hydrogen concentrations within the fuel exhaust stream are detected by a detector (68) which communicates the changes to a controller (108) for controlling a rate of fuel supply to the fuel cell (12). A porous sensor water transport plate (74) cools, humidifies delivers and removes liquid from the sensor cell (12).

摘要： Water (9) in a fuel cell accumulator (10) is kept above freezing by a hydrogen/oxygen catalytic combustor (13) fed hydrogen through a mechanical thermostatic valve (25) in thermal communication (26) with the container (10) or the air nearby, and connected to hydrogen (28), optionally in series with a timer valve (183). The combustor may comprise an ejector (32) having hydrogen through its primary inlet (31) drawing air through a secondary inlet (33), or a diffusion combustor having a catalyst (38), including TEFLON® to permit water generated by combustion to flow by gravity out of the catalyst, spaced from a heating surface (30), and a diffusion control device (40); low partial pressure of oxygen at the catalyst causing diffusion through the device. Combustion vapor condenses on a surface (146) and is led by hydrophilic woven carbon paper (126) and wicking material (133) downwardly, through a disk (140) and plugs (147) either to ambient, to a salt canister (190), or to a porous hydrophilic mixer (200) for mixture with antifreeze (206).
