摘要： An integrated fuel cell power generation system comprises a fuel cell stack having a humidification section and an electrochemically active section. The humidification section imparts water vapor to an inlet hydrogen containing fuel stream and an inlet oxygen containing oxidant stream. The electrochemically active section comprises fuel cells for promoting the electrocatalytic conversion of the humidified fuel and oxidant streams to electric current and product water. The electrochemically active section also includes a coolant water stream for absorbing heat generated in the active section. The system includes a heat exchanger for removing heat from the coolant water stream exiting the active section, a water separator for removing water from the oxidant stream exiting the fuel cell stack, and a coolant reservoir for receiving the removed water stream from the water separator and from the heat exchanger. The coolant water stream is drawn from the coolant reservoir.

摘要： The invention disclosed is a novel fluid flow field plate for use in a solid polymer electrolyte fuel cell. The plate includes in a major surface thereof, a continuous open-faced fluid flow channel which traverses the central area of the plate surface in a serpentine manner. The channel has a fluid inlet at one end for receiving a reactant gas and a fluid exhaust at the other end for removing excess reactant gas and reaction products from the cell.
