Title: Manfred Diehl: Innovator in Fuel Cell Technology
Introduction
Manfred Diehl is a prominent inventor based in Frankfurt-am-Main, Germany. He has made significant contributions to the field of fuel cell technology, holding a total of 18 patents. His innovative work focuses on the development of membrane electrode assemblies and processes for fuel cells.
Latest Patents
One of Diehl's latest patents is a process for producing a membrane electrode assembly for fuel cells. This process involves a polymer electrolyte membrane with two parallel surfaces. The first surface is combined with a catalyst layer and a water-repellent gas distribution layer, while the second surface is similarly equipped. The catalyst layers are created using inks that contain electrocatalysts, solvents, proton-conducting ionomers, and optional water-repelling agents. The application of these layers is done successively, ensuring that the opposite surface of the membrane is supported during the process.
Another notable patent is for applying electrode layers to a polymer electrolyte membrane strip for fuel cells. This process allows for the continuous printing of electrode layers on both sides of the membrane in a desired pattern. The printed layers are dried at elevated temperatures immediately after printing, ensuring accurate positioning of the patterns on both sides.
