Method for the preparation of catalyst-coated membranes |
| abstract |
The present invention is directed to a method for preparing an integral 3-layer catalyst-coated membrane (CCM) for use in electrochemical cells, e.g. PEM (polymer-electrolyte membrane) fuel cells. The process comprising the steps of preparing a first catalyst layer on a supporting substrate, subsequently coating the first catalyst layer with an ionomer dispersion to form an ionomer layer (membrane), and applying a second catalyst layer on top of the ionomer layer. The ionomer dispersion applied in the membrane coating step has a low viscosity in the range of 10 to 400 centipoises (cP) and an ionomer concentration in the range of 15 to 35 weight-%. With this method, CCMs with improved electrochemical performance and reduced cathode resistance are manufactured.. |
