PEMFC MEA Introduction & Application  
   
 

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.
