Abstract: In solid polymer fuel cells employing framed membrane electrode assemblies, a conventional anode compliant seal is employed in combination with a cathode non-compliant seal to provide for a thinner fuel cell design, particularly in the context of a fuel cell stack. This approach is particularly suitable for fuel cells operating at low pressure.

Abstract: A fuel cell stack assembly is disclosed comprising: a fuel cell stack comprising a first end plate, a second end plate, and a plurality of fuel cells interposed between the first and the second end plates; and a compression band which urges the first end plate towards the second end plate along a first face of the fuel cell stack and also along an opposing second face of the fuel stack in a stacking direction thereof in at least two passes on each face of fuel cells stack, thereby applying a compressive force upon the plurality of fuel cells in the fuel cell stack.

Abstract: A method is provided for operating a fuel cell stack with improved performance recovery from sub-saturated conditions, the method comprising setting an alert for the performance recovery of the fuel cell stack, performing at least one oxidant starvation by supplying oxidant at a stoichiometric ratio below 1 to the fuel cell stack in at least one pulse for a preset amount of time and at low current while the fuel cell stack does not generate power. The fuel cell system with an improved performance recovery comprises a shorting circuit which is connected to the fuel cell stack at predetermined times (startup, shutdown or standby mode) and an air compressor powered by a DC-DC converter which supplies a predetermined number of oxidant pulses of a predetermined duration to the fuel cell stack.
