Abstract: A bipolar plate assembly for a fuel cell includes a first bipolar sheet having elongated lands formed thereon each defining secondary channels therein. The first bipolar sheet further includes primary channels formed between adjacent elongated lands. The first bipolar sheet includes an active area at which fluids flowing through the primary and secondary channels electrochemically react with an adjacent gas diffusion layer of the fuel cell. Top surfaces of the elongated lands include injectors formed as a hole in the top surfaces and located in the active area of the first bipolar sheet. Fluid flowing through the secondary channels is forced through the injectors, subsequently into the adjacent gas diffusion layer, and subsequently into and adjacent primary channel.

Abstract: The present disclosure generally relates to systems and methods for operating a fuel cell system including operating a fuel cell comprising a membrane electrode assembly, dynamically operating an air handling system comprising an air compressor which controls stack pressure and air flow in the fuel cell stack system, determining a parasitic loss in the fuel cell system based on the air handling system, and operating the fuel cell system in transient conditions based on a transient system curve. The transient system curve may be based on a relationship between the stack pressure and stack temperature, and the parasitic loss.

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.
