A small PEM fuel cell of area 25 cm2 has an open circuit hydrogen consumption of 0.0085 cm3 /sec. Accounting for activation and internal crossover losses, estimate and plot the polarization curve. Standard temperature and pressure conditions can be assumed. Ohmic and mass transport losses may be neglected.
