| 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 particular the catalyst ( 11 ) is embedded in the anion conducting polymer ( 12 ), and the cation conducting polymer ( 14 ) encloses regions of the anion conducting polymer ( 12 ).
