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 cat...
A solid polymer fuel cell stack power assembly comprising: (a) a plurality of fuel cells stacked one atop another, each of said fuel cells comprising: (i) a solid polymr electrolyte membrane; (ii) means forming an anode on one face of said electrolyte membrane, and means forming a cathode of an opposite face of said electrolyte membrane; (iii) a porous anode flow field plate disposed adjacent to said anode, said anode flow field plate having a contoured surface facing said anode with a plurality of grooves forming a hydrogen reactant flow field, and a pl...
