The effect of hydrogen crossover on open-circuit voltage in polymer electrolyte membrane fuel cells

Even though the measured open-circuit voltage in a H 2–O 2 PEM fuel cell is invariably about 200–250 mV lower than that predicted from thermodynamics (1.229 V at 25 °C), there is no unequivocal explanation of this phenomenon available in the literature, although several hypotheses exist. Based on a...
