A method of forming a membrane electrode assembly (MEA) includes first bonding a first electrode layer to a first side of an ion-exchange membrane. The method may further include protecting a second side of the membrane with a release sheet. The method may further include removing the release sheet and bonding the second side of the membrane to a first side of a second electrode layer. The method may further include positioning venting members on a second side of the second electrode layer to remove at least one of a liquid and a vapor that may be generated during the bonding process. In another embodiment an electrocatalyst can first bond to at least one side of the membrane, and subsequently, to a gas diffusion layer. An opposing side of the membrane can bond to an electrode layer in aqueous state.

Method of forming membrane electrode assemblies for electrochemical devices

The present invention is related to methods of making membrane electrode assembly components. The methods include transferring a catalyst layer to a polymer electrolyte membrane or a gas diffusion layer. Methods of making membrane electrode assemblies with these components are also disclosed.
