Abstract (en)
[origin: WO2016206840A1] The technology disclosed here relates to a fuel cell having an ion-selective separator, a gas diffusion layer and a separator plate. The separator plate forms, together with the gas diffusion layer, at least one gas-conducting flow field. At least one first convergent duct section and at least one first divergent duct section are formed in the flow field, wherein the convergent duct section lies adjacent to the divergent duct section. A first barrier is provided between the convergent duct section and the divergent duct section such that the gas flows at least partially through the gas diffusion layer in order to pass directly from the convergent duct section into the divergent duct section. At least one additional convergent duct section, at least one additional divergent duct section and at least one additional barrier are provided downstream of the at least one convergent duct section and/or downstream of the at least one divergent duct section.
