PROBLEM TO BE SOLVED: To provide a compact apparatus comprising a fuel cell unit and a component such as a heat exchanger, a reformer, a preheater or an afterburner, and providing good flow characteristics.SOLUTION: An apparatus includes a fuel cell stack 2 including a plurality of fuel cells defining a longitudinal axis and a main flow direction 100 coaxial to the longitudinal axis. The apparatus furthermore includes a component (a heat exchanger 1, a reformer 3) comprising a first flow conduit arranged parallel to the main flow direction. The first flow conduit includes a first fluid inlet and a first fluid outlet arranged along the main flow direction, at both ends of the component. The component 1, 3 is arranged adjacent the fuel cell unit 2. A fluid flow flows substantially parallel to the longitudinal axis of the apparatus in the first fluid conduit of the component 1, 3 and in the fuel cell unit 2 when passing from the component to the fuel cell unit or vice versa. |
