氢电极

In the charge-discharge tests, for the electrode irradiated by light and charged with current simultaneously, the discharge time is about 11.4 h, much longer than that (about 8.7 h) charged only with current, indicating obvious photo-assisted chargeability of the electrode. The additional discharge capacity is contributed to the photocharge of photogenerated electrons and holes.
