MANUFACTURE OF A GAS DIFFUSION ELECTRODE

摘要

A novel process for the manufacture of a gas diffusion electrode comprising the steps of a) application of a catalyst ink to a gas diffusion substrate; b) firing; c) application of a proton-conducting polymer solution; and d) drying; characterised in that the proton-conducting polymer solution comprises one or more solvents selected from the group of solvents with structure (A) wherein R<1>, R<2> and R<3> are independently chosen from H, methyl, ethyl, n-propyl and isopropyl is disclosed. A novel process for the manufacture of a membrane electrode assembly is also disclosed.
