Abstract
A fuel cell system has a single-stage or multistage gas generation unit for producing a hydrogen-rich gas from an untreated fuel, a single-stage or multistage gas cleaning unit, at least one fuel cell and a single-stage or multistage exhaust-gas treatment unit for converting the fuel cell exhaust gases as completely as possible. At least two sub-units of the fuel cell system are connected to one another mechanically and in terms of flow by means of a connecting plate.
Claims13
A fuel cell system, comprising:
- a single-stage or multistage gas generation unit for producing a hydrogen-rich gas from an untreated fuel;
- a single-stage or multistage gas cleaning unit for removing carbon monoxide from the hydrogen-rich gas;
- at least one fuel cell unit;
- and
- a single-stage or multistage exhaust-gas treatment unit for converting the fuel cell exhaust gases;
- wherein
- at least two units of the fuel cell system are connected to one another mechanically and in terms of flow by means of a connecting plate;
- the connecting plate is formed with opposite sides thereof parallel to a principal plane;
- at least one flow channel is provided in the connecting plate, which flow channel runs substantially parallel to the principal plane;
- the units are arranged on one side or on opposite sides of the connecting plate;
- and
- the units are in flow communication with the at least one flow channel via bores arranged substantially perpendicular to the principal plane.
