NEW CATALYTIC MEMBRANES FOR USE IN FUEL CELLS AND ELECTROLYZERS

This is a new process for obtaining membrane electrodes (MEA) that are used in fuel cells and electrolyzers. These MEAs constitute the real core of these devices. The membranes covered by the patent are made with polymeric materials and new generation catalytic elements, with excellent performance, long stability, reliability and durability, and low cost. They do not contain precious metals as catalysts and do not use other catalysts or proprietary base polymers. They have equivalent performance and performance to current ones using commercial Nafion® membranes and Pt catalyst or other precious metals, but at a significantly lower cost (about 50% of the current cost).
