    Abstract: A separator plate (10) is provided for use in a fuel cell stack, having a fuel gas flow field adjacent one surface and an oxidant gas flow field adjacent the other surface. The flowpaths of the flow fields comprise parallel flow channels (24) extending longitudinally and interconnected at their ends to form the serpentine flowpaths. The interconnections are formed by an array of spaced interconnection couplings (16, 18), that may be depressed cavities in the separator plates. The couplings for the oxidant gas flow channels are offset from those for the fuel flow channels. The interconnecting couplings may be formed by stamping, machining, or moulding the separator plate. The fuel cells in the stack are advantageously PEM-type fuel cells.

    Abstract: An electrochemical fuel cell assembly includes a membrane electrode assembly which comprises an anode, a cathode having a surface thereof exposed to ambient air, and an ion exchange membrane interposed between the anode and the cathode. A seal forms a gas-impermeable barrier around the anode to which a gaseous fuel stream is supplied. The assembly further includes a thermally conductive plate having a plurality of thermally conductive members of fins extending from a major surface of the plate. The thermally conductive members contact portions of the exposed cathode surface. Adjacent thermally conductive members cooperate with the plate and the exposed cathode surface to form air conducting channels. Heat generated exothermically in the membrane electrode assembly is dissipated to the atmosphere through the thermally conductive members.

In a third embodiment, a reference voltage equal to the voltage across one group is compared to the voltage across each of the other fuel cell groups. In a fourth embodiment, the voltage across each group is compared as a reference voltage to the voltage across an adjacent fuel cell group. Other embodiments comprising various combinations of the first, second, third and fourth embodiments are also provided. An alarm is activated, and supply of fuel to the cells discontinued, when the measured voltage for a fuel cell group varies from the reference voltage by more than a predetermined voltage differential.
