Abstract:
A method for determining a rate of accumulation of nitrogen in an anode side of a fuel cell stack. The method includes determining a concentration of nitrogen in an anode loop and determining a number of moles of nitrogen in the anode loop. The method also includes determining a rate of accumulation of nitrogen in the anode loop and determining a permeability factor of nitrogen through fuel cell membranes in the fuel cell stack using the determined rate of accumulation of nitrogen in the anode loop.
