| 主权项 | 1. A method for the use of a proton exchange membrane fuel cell, composed of a polymer membrane and electrodes present on either side of the membrane, comprising the steps of: measuring the initial performance of the cell; monitoring the performance of the cell over time; and reversing the electrodes corresponding to an anode and a cathode, respectively, during use, when a predetermined threshold of the performance is reached; wherein the purity of a gas provided at the anode determines a frequency at which the performance of the cell is monitored, whereby the performance is monitored at least once a minute when the gas has impurities, and the performance is monitored at least once an hour when the gas is pure. | ||
