| 摘要 |
A liquid electrolyte fuel cell system (10, fig 1) comprises at least one fuel cell 80, each fuel cell comprising a liquid electrolyte chamber 82 between opposed electrodes, the electrodes being an anode 83 and a cathode 84, and a duct (36, fig 1) for supplying a gas stream to a cathode gas chamber 86 adjacent to the cathode 84. The system also comprises a supply 92 of hydrogen peroxide, which is introduced into the cathode gas chamber 86. The hydrogen peroxide may be introduced within an aqueous liquid supplied to a humidification chamber (52, fig 1). The hydrogen peroxide may be sprayed through a nozzle (74, fig 4) into the gas stream. Alternatively it may be introduced into a hydrophilic layer 90 on a surface of the cathode 84 facing the cathode gas chamber 86. |
