The invention relates to a solid oxide fuel cell system, wherein planar fuel cells are arranged in stacked form and in this respect an integrated post-combustion of non-oxidized components, or of not fully oxidized components, in the exhaust gas can take place. The fuel cells of a system in accordance with the invention have a cathode-electrolyte-anode unit. A bipolar plate is arranged between two respective fuel cells and channels for the supply and removal of a fuel gas to anodes and of an oxidizing agent to cathodes are present. The exhaust gases at the anode side or at the cathode side are introduced via internal additional channels or directly into an afterburner in which a catalytic post-oxidizing of the exhaust gas mixture formed with the exhaust gas at the anode side and at the cathode side takes place. In this respect, a catalytic afterburner is associated with every single fuel cell or with a group formed of a plurality of fuel cells and the afterburners are arranged so that exhaust gas discharged from a fuel cell at the anode side or at the cathode side can enter directly into an afterburner.

Solid oxide fuel cell system

A fuel cell stack with a plurality of fuel cell elements which are layered on one another with separating plates located between the fuel cell elements. Inside channels are formed to supply a combustion gas and discharge the exhaust gas. The fuel cell stack is characterized in that, on a first side of the fuel cell elements, several parallel lengthwise channels are formed for routing of the combustion gas, and on the ends of the channels, a distributor zone is formed which connects the supply channel to the respectively first ends of the lengthwise channels, and a collecting zone is formed which connects the discharge channel to the second ends of the lengthwise channels, and that there is an oxidizer guide on the second side of the fuel cell elements, the oxidizer guide running in the direction of the lengthwise channels.

Fuel cell stack

A method for the production of a fuel cell stack, involving the following steps: a) piling up the fuel cell stack () and (b) putting together the fuel cell stack () while heating and compressing the piled fuel cell stack (). At least one regulated force is applied to the piled fuel cell stack () during the compression thereof.

Process and device for producing a fuel cell stack while applying a controlled force to the assembled stack

A roof module () for a motor vehicle, with an integrated climate control system (). Furthermore, the roof module () includes a fuel cell system (). The roof module () is preferably a pre-mounted complete motor vehicle roof with bordering modules, preferably with extra integrated functions.
