  • Method of forming membrane electrode assemblies for electrochemical devices
    Patent number: 8586265
    Abstract: 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.
