| 摘要 |
A cathode layer structure for a solid polymer fuel cell is disclosed. It comprises a composite cathode layer (48) of catalyst (11), anion ion conducting polymer (12) and cation conducting polymer (14). The interface between the anion ion conducting polymer (12) and the cation conducting polymer (14) is located entirely within the cathode layer (48). In particula r the catalyst (11) is embedded in said anion conducting polymer (12), and the cation conducting polymer (14) encloses regions of said anion conducting polymer (12). |
