| 摘要 |
The present invention is to provide a high-performance electrode for fuel cells. Disclosed is an electrode for polymer electrolyte fuel cells, comprising a polymer electrolyte material and a metal catalyst carried on carbon, wherein the polymer electrolyte material is an electrolyte material represented by the following general formula: and wherein, in a graph showing a relationship between a scattering vector magnitude and a scattering intensity, both of which are obtained by measuring the electrode in an air atmosphere by a smaller-angle neutron scattering method, the electrode has such a hydrophilic domain dispersibility that the maximum value of ratios of scattering intensities to baseline intensities for all ion peaks is in a range of more than 1.00 to 1.42. |
