Consider a 10-plate fuel cell stack at an anode stoi- chiometry of 1.2 with 20 A current generated in the stack and a stack voltage of 6.0 V. As an engineer, you have a choice to install a recirculation pump to recycle the unused hydrogen from the anode exhaust back into the anode to increase the effective fuel utilization to 100%. However, the pump required 60 W of parasitic power to operate con- tinuously. Is installation of the pump justified?
