METHOD FOR PRODUCING GAS DIFFUSION ELECTRODE, AND METHOD FOR PRODUCING MEMBRANE ELECTRODE ASSEMBLY (MEA) |
摘要 |
Provided is a method for producing a gas diffusion electrode, with which it is possible to more effectively improve electrode performance, in cases in which a core-shell catalyst is used as an electrode catalyst. This method for producing gas diffusion electrode comprises: a first step in which a support layer having electron conductivity, water-repellency and gas diffusion properties is soaked in water; a second step in which the constituent materials of ink for forming a catalyst layer are put into a mixer and mixed by agitation to prepare an ink for forming a catalyst layer; and a third step in which the ink for forming a catalyst layer is used to form a catalyst layer on the surface of the support layer obtained in the first step. The ink for forming the catalyst layer contains a core-shell catalyst, a polyelectrolyte, water and alcohol. However, the alcohol is only a polyvalent alcohol, and C1-3 monovalent alcohols are not included. |
