N2 - Fuel cells are sensitive dynamic systems. Their dynamics and performance characteristics must be considered when designing cells, stacks, and control systems. When considering a battery and resistor in series as part of an electrical circuit, the internal resistance of the fuel cell varies with the area of the cell. The value of Rint·Acell (Rint = internal resistance) is constant with area, but varies with the state of hydration of the membrane and the quality of the electrode-membrane interfaces. Reducing Rint by increasing the fuel cell area is equivalent to reducing the Rint of the battery by placing several batteries in parallel. The resistance values add for either fuel cells or batteries in series. This is an abstract of a paper presented at the ACS Fuel Chemistry Meeting (Washington, DC Fall 2005).
