文摘

Five identical single cells were used for constant and dynamic long-term testing. Time-based and hydrogen-based degradation rates are improved by current cycling. Intermittent operation of PEM water electrolysis is beneficial for durability. PEM water electrolysis is suited for operation with intermittent power sources. Degradation phenomena were analyzed and located.
