ELECTRODE FOR FUEL CELL HAVING TWO KINDS OF HYDROPHILICITY AND METHOD FOR PREPARING THE SAME AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL COMPRISING THE SAME |
摘要 |
An electrode for a fuel cell includes a gas diffusion layer contacting with a separator having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane. The catalyst layer of the electrode has two portions with different hydrophilicities. A portion of the catalyst layer that faces a channel has a higher hydrophilicity than a portion that does not face a channel. This electrode may control hydrophilicity of the catalyst layer differently according to locations, so it is possible to keep an amount of moisture in an electrode in a suitable way, thereby improving the performance of the cell. |
