Abstract
A fuel cell has 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 channel web of the separator plate has an end with an upper face and an end face. The end face is designed to divide a flow impinging on the end face of the channel web in a first direction into two partial flows. The end face is designed to deflect a liquid of the flow impinging on the end face adjacently to the upper face in such a manner that the liquid is spaced further from the upper face after deflection than before deflection.
