Abstract
Electrodes for an electrochemical cell such as a proton exchange membrane (PEM) fuel cell are treated with steam or a hot solution before they are bonded to a membrane to form a membrane-electrode assembly. Such a treatment effectively increases the performance of the electrodes when they are subsequently tested within the PEM fuel cell. Improved performance is also observed using this technique with a catalyst-coated membrane and a membrane-electrode assembly.
