答案：【计分规则】: (2) At the anode a catalyst oxidizes the fuel, usually hydrogen, turning the fuel into a positively charged ion and a negatively charged electron.The electrolyte is a substance specifically designed so ions can pass through it, but electrons cannot. The freed electrons travel through a wire creating the electric current.The ions travel through the electrolyte to the cathode. Once reaching the cathode, the ions are reunited with the electrons and the two react with a third chemical, usually oxygen, to create water or carbon dioxide.
