摘要： A fuel cell stack (31) includes a plurality of fuel cells (9) each having an electrolyte such as a PEM (10), anode and cathode catalyst layers (13, 14), anode and cathode gas diffusion layers (16, 17), and water transport plates (21, 28) adjacent the gas diffusion layers. The cathode diffusion layer of cells near the cathode end (36) of the stack have a high water permeability, such as greater than 3x10-4 g/(Pa s m) at about 80°C and about 1 atmosphere, whereas the cathode gas diffusion layer in cells near the anode end (35) have water vapor permeance greater than 3x10-4 g/(Pa s m) at about 80°C and about 1 atmosphere. In one embodiment, the anode gas diffusion layer of cells near the anode end (35) of the stack have a higher liquid water permeability than the anode gas diffusion layer in cells near the cathode end; a second embodiment reverses that relationship.

摘要： A fuel cell power plant (9, 60) includes a plurality of fuel cells in a stack (10, 61) each having coolant channels (13, 64) with coolant outlets (27, 80) directed to a water gas separator (40, 77), a gas outlet (45, 82) being connected to an orifice (47, 84) through a pressure detector (46, 83). Detection of excessive pressure, indicative of excessive ingestion of gas into the coolant, causes a controller (39, 102) to control operating parameters of the fuel cell stack, such pressure or shutdown of coolant or reactant gas, to avoid fuel cell damage due to the gas ingestion.

摘要： A fuel cell stack (10) includes a reaction portion (20) having an end cell (12) secured adjacent to a current collector (30). The collector (30) has a sensible heat no greater than a sensible heat of the end cell (12) and an electrical resistivity no greater than 100 micro-ohms centimeters. An insulator (40) is secured adjacent the collector (30) and has a thermal conductivity that is no greater than 0.500 Watts per meter per degree Kelvin. Because of the low sensible heat of the current collector (30) and low rape of heat transfer of the insulator (40), heat does not readily leave the end cell (12) resulting in a rapid heating of the end cell (12), thereby avoiding freezing and accumulation of product water in the end cell (12) during start up in subfreezing conditions.

摘要： The invention is a hydrogen passivation shut down system for a fuel cell power plant (10). An anode flow path (24) is in fluid communication with an anode catalyst (14) for directing hydrogen fuel to flow adjacent to the anode catalyst (14), and a cathode flow path (38) is in fluid communication with a cathode catalyst (16) for directing an oxidant to flow adjacent to the cathode catalyst (16) of a fuel cell (12). Hydrogen fuel is permitted to transfer between the anode flow path (24) and the cathode flow path (38). A hydrogen reservoir (66) is secured in fluid communication with the anode flow path (24) for receiving and storing hydrogen during fuel cell (12) operation, and for releasing the hydrogen into fuel cell (12) whenever the fuel cell (12) is shut down.

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： The water outlet (68) of fuel cell stack (37) is connected to suction inlet (200) of an eductor (202) having a primary flow of pressurized (208) immiscible fluid. The fluid mixture is applied to an inlet (240) of a separator (231); the immiscible fluid (and gas originally entrained with the water) passes through a porous hydrophobic medium (242) to a first outlet (244) of a separator (231 ) to return to the pump; and the water passes from the inlet through a porous hydrophilic medium (247) to a second outlet (248), for return to the stack; the gas is vented (212). A deionizer (175) is located either upstream or downstream of the separator.

摘要： A cascaded fuel cell stack (9a) includes a plurality of groups (10-12) of fuel cells (13) connected electrically in series by means of conductive separator plates (58, 59) and current collecting pressure plates (56, 57). Each group has an inlet fuel distributing fuel inlet manifold (17a, 19c, 20c), a fuel exit manifold (19a, 20a) of each group except the last feeding the inlet manifold of each subsequent group. A microcontroller responds to signals from a plurality of voltage sensing devices (48a - 48c) to cause corresponding switches (50a - 50c) (a) to connect each group, and all preceding groups in the sequence, to a voltage limiting device (VLD) (45), or (b) to connect each group to its own (VLD) (45A -45C), in response to sensing a predetermined average cell voltage across the corresponding group. When normal operation occurs, the microcontroller connects the main load and disconnects the voltage limiting device (53) (25).
