In fuel cells operated with damp operating gases, water condenses out as the operating gas flows from the damping device to the fuel cell block. Typically, the condensed water runs into the fuel cells and impairs their operation. A fuel cell block according to the invention includes fuel cells, a an operating gas delivery line, and a condensed water separator connected to the operating gas delivery line for preventing the condensed water from flowing into the fuel cells.
