More Information
Summary:A porous catalyst layer formed from discrete particles of unsupported metal, wherein at least 80%, suitably at least 90%, of the discrete particles have a mass of from 1 to 1000 zeptograms, and wherein the catalyst layer has a metal volume fraction of less than 30% and a metal loading of less than 0.09 mg/cm2 is disclosed. The catalyst layer is suitable for use in fuel cells and other electrochemical applications.
