Abstract
A fuel cell assembly includes a first bipolar plate, a second bipolar plate, and a diffusion-electrode assembly. A first top surface of the first plate includes a first seal protruding upwardly and a first raised feed channel adjacent the first seal and protruding upwardly. A second bottom surface of the second plate includes a second seal protruding downwardly and a second raised feed channel adjacent the second seal and protruding downwardly. The diffusion-electrode assembly includes a membrane layer having a membrane frame extending therefrom and two gas diffusion layers. The first and second plates are arranged parallel, the first and second seals align with each other, and the first and second raised feed channels align with each other. The first and second raised feed channels contact the membrane frame arranged therebetween so as to prevent mechanical deformations of the first and second plates.
