Carl A Reiser, Richard D Sawyer: Solid polymer electrolyte fuel cell stack water management system. International Fuel Cells Corporation, W W Jones, September 6, 1988: US04769297 (99 worldwide citation)

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 throug ...
