 Product Outlines
 Proton Exchange Membrane Fuel Cell Membrane Electrode
Assembly (PEMFC MEA) ,the most important component for direct hydrogen or
reformate hydrogen fuel cell, consists of anode and cathode catalyst on both
sides of proton exchange membrane, generating electric power through the
electrochemical reaction occurred on anode and cathode.
