ELECTROCATALYST LAYERS FOR FUEL CELLS AND METHODS OF MAKING ELECTROCATALYST LAYERS FOR FUEL CELLS

摘要

An electrochemical fuel cell is disclosed. The electrochemical fuel cell comprises a membrane electrode assembly comprising: an anode having an anode gas diffusion layer and an anode electrocatalyst layer; a cathode having a cathode gas diffusion layer and a cathode electrocatalyst layer; and a proto n exchange membrane disposed between the anode and the cathode. At least one of the anode electrocatalyst layer and the cathode electrocatalyst layers c omprises an electrocatalyst and polyfurfuryl alcohol. The polyfurfuryl alcoh ol may be distributed uniformly or non-uniformly within the electrocatalyst layer. Methods of making the electrocatalyst layer having an electrocatalyst and polyfurfuryl alcohol are also disclosed.
