Method for making membrane-electrode assembly for fuel cell and method for making fuel cell system comprising the same |
摘要 |
A membrane-electrode assembly for a fuel cell of the present invention includes an anode and a cathode facing each other, and a polymer electrolyte membrane interposed therebetween. At least one of the anode and the cathode includes a catalyst layer and an electrode substrate. The catalyst layer includes a catalyst and a porous ionomer. The polymer electrolyte membrane contacts one side of the catalyst layer and the electrode substrate contacts the other side of the catalyst layer. |

1. A method for manufacturing a membrane-electrode assembly, comprising:
preparing an anode and a cathode, at least one of the anode and the cathode comprising:
a catalyst layer comprising a catalyst and a porous ionomer layer, the catalyst layer formed by a process comprising:
preparing a catalyst slurry comprising the catalyst, an ionomer, a plasticizer and a dispersion solvent, wherein, the plasticizer is at least one polymer selected from the group consisting of a C1 to C10 polyalkyleneglycol; a C1 to C10 poly(alkyl)acrylic acid; an aromatic or fluorine polymer having a sulfonic acid group; and a cellulose-based polymer, the weight ratio of the plasticizer to the ionomer ranges from about 20:80 to 70:30;coating the slurry onto an electrode substrate; andextracting the plasticizer wherein the plasticizer is extracted by dipping the coated electrode substrate in an extraction solvent; andthe coated electrode substrate enabling a reactant to diffuse into the catalyst layer; and preparing a polymer electrolyte membrane interposed between the anode and the cathode. |
