氢在阴极氧化成水产生电子，电子通过外部电路又回到电池阳极；
The oxidation of hydrogen to water at the cathode yields electrons, which pass through an external circuit and reenter the cell at the anode;
电解：使电流通过电解质溶液而在阳极，阴极引起氧化还原反应的过程。
Electrolysis: make the current through the electrolyte solution at the anode and cathode cause REDOX reaction process.
阴极物质主要为氧分子或者过氧化氢，随后在电池反应中消耗，与阳极反应共同产生电能。
In the cathode, substances such asmolecular oxygen or hydrogen peroxide are subsequently reduced in this processand so, in combination with the reaction at the anode, generate electricalpower.
