Fuel cell electrode catalyst solution and production method therefor |
摘要 |
The invention improves operability in forming a catalyst electrode, and improves performance of a fuel cell. A catalyst-loaded carbon is dispersed in a mixed solution of an azeotropic solvent and ion exchanged water. An electrolyte solution is added to the dispersed solution. A solvent, such as ethanol or the like, is added to adjust the viscosity and the water content of the solution, thereby providing an electrode catalyst solution. The use of the obtained solution as an ink for forming a catalyst layer through printing improves printing characteristic and drying characteristic.
