Cross-over leakage in fuel cells is determined by comparing the concentration of carbon dioxide in the oxidant inlet stream and cathode effluent. The amount of carbon dioxide in the oxidant stream of a fuel cell should remain constant, barring leakage problems. Therefore, if the carbon dioxide concentration changes, a leakage problem exists. Since this process is in-line, the staff operating the fuel cell stack is virtually immediately alerted to a potential leakage problem.
