A fuel cell system in which water can be accurately supplied in accordance with the flow rate of fuel gas supplied to the reformer to allow efficient reforming without using a flow meter measuring the flow rate of water. In the fuel cell system in which fu...

The compact bio-reactor fuel cell system has a bio-reactor (16) arranged above a fuel cell (14) and a vertical structure with at least two levels. The system has a sedimentation system (15) and a drying system (13) underneath the bio-reactor and is of modu...

Solid oxide fuel cell with a planar support (2) in form of a porous plate structure supporting on one planar surface a layer of electrode active material (8) and with internally elongated gas supply channels (4) formed inside the structure.

A fuel cell manifold arrangement (5) includes a fuel cell stack (103) and a manifold enclosure (10) connected to and sealed to an inlet side of the fuel cell stack (103) and defining with the stack a gas plenum (21) for receiving a fuel gas (14) for the fu...
