Patent ID: 7226689

Claim:
A method of making a membrane electrode assembly for an electrochemical fuel cell comprising: providing a first gas diffusion layer; providing a one-sided catalyst coated membrane having a first catalyst layer coated on an ion-exchange membrane; providing a gas diffusion electrode having a sintered catalyst layer coated on a second gas diffusion layer, wherein the sintered catalyst layer is the anode catalyst layer and wherein sintering of the anode catalyst layer is at a temperature between about 330° C. and 420° C.; bonding the first gas diffusion layer to the one-sided catalyst coated membrane such that the first catalyst layer is interposed between the first gas diffusion layer and the ion-exchange membrane; and bonding the gas diffusion electrode to the one-sided catalyst coated membrane such that the sintered catalyst layer is interposed between the second gas diffusion layer and the ion-exchange membrane.
