Multi-layer membrane-electrode-assembly (ML-MEA) and method for its manufacture |
摘要 |
The invention relates to the field of electrochemical cells and fuel cells, more specifically to polymer-electrolyte-membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC). A multi-layer membrane-electrode-assembly (ML-MEA) comprising two electrically conductive bipolar plates and a membrane-electrode-assembly (MEA) bonded together by means of an electrically insulating adhesive material is disclosed. The adhesive material, preferably a polyurethane-based system, is in direct contact with the protective film layers attached to front side and the back side of the MEA, thus contamination of the ionomer membrane and/or the electrode layers with adhesive components is avoided. Multi-layer MEAs with improved long term stability and life time are obtained. The products are used for the manufacture of low temperature PEMFC and DMFC stacks.
