PROTON-CONDUCTING CERAMIC MEMBRANES ON THE BASIS OF ZIRCONIUM PHOSPHATES, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF IN MEAS AND FUEL CELLS

摘要

The invention relates to proton-conducting ceramic membranes on the basis of zirconium phosphates, methods for the production thereof, and the use thereof in MEAs and fuel cells. The inventive ceramic membranes represent a new class of proton-conducting membranes. In a first step of a special method, nanoscale zirconium phosphate is produced in a microjet reactor. Said material is then applied on a flexible carrier as a suspension and solidified, whereby a cation/proton-conducting membrane is obtained which is impermeable for materials, flexible and can be used in a fuel cell without any problem.
