| 摘要 |
A fuel cell gas separator member (10) comprises a layer (22) of copper or copper-based alloy having a layer (29) of oxidation-resistant material such as Al2O3 on the cathode side (30). A protective layer (31) may also be provided on the anode-side (26) of the copper or copper-based alloy layer. The copper-based alloy may b e aluminium bronze in which case the oxidation-resistant layer may form automatically. Alternatively, the copper or copper-based allo y layer (22) may be wrapped in a foil (29, 31) of heat resistant steel. Other possibilities are disclosed. |
