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.
