During a first market analysis several years ago, Professor Birgit Scheppat from RheinMain University conducted extensive tests and evaluations of fuel cell stacks available at the time (see October 2010 issue of German-language magazine HZwei). On behalf of Hessen Agentur and in collaboration with the H2BZ initiative, she examined which challenges customers face

Simplified Production Method for PEM Fuel Cells
The heart of PEM fuel cells is the membrane electrode assembly (MEA), which has so far been produced by using only polymer electrolyte membranes. The manufacture of these membranes, however, is highly complex and expensive, limiting MEA production to a few companies around the globe. An innovative method discovered by researchers from the Department of Microsystems Technology (IMTEK) at the University of Freiburg makes the membrane process technology obsolete
