Abstract

A fuel cell assembly includes a fuel cell configuration having a solid electrolyte-based fuel cell with terminal contacts tapping an electrical voltage from the fuel cell configuration between which the fuel cell is disposed. An assembly has an electrically conductive component and another component disposed between a first terminal contact and the electrically conductive component on the side of the first terminal contact away from the fuel cell and has a lower electrical conductivity than that thereof. A supply duct transports a fluid medium connecting the first terminal contact to the electrically conductive component through the other component. The electrically conductive component is connected to the first terminal contact and/or a voltage supply adjusting an electrical potential on the electrically conductive component to an electrical potential on the first terminal contact. There is a maximum potential difference of 3 volts between the electrically conductive component and the first terminal contact.
