The fuel cell system has a fuel cell module [4] that consists of a number of cascaded part modules [4a,b,c]. A fuel gas chamber [26] of the last part module has a feedback line [R] for surplus coupled to the cathodes of the modules. This provides an exhaus...

Solid electrolyte fuel cell is operated with a fuel containing hydrogen and the method involves removing carbon dioxide form the anode output gas flow, which contains at least hydrogen and carbon dioxide, using liquefaction. The residual gas is oxidized af...

A fuel cell system is provided with a fuel cell having a fuel electrode and an air electrode, an air supply section supplying air to the air electrode, an air supply passage connecting the air supply section and the air electrode, an air exhaust passage ex...

The system has the fresh cathode gas compressed (1) and fed to the fuel cell (BZ). At inlet and outlet there are moisture sensors (3,4) that control a compressor (2) coupled into a feedback loop to provide mixing with the unused cathode gas. This holds the...

The present invention is carried out to improve the starting capability of a fuel cell at low temperatures. The fuel cell system comprises a fuel cell 1 which generate electric power by supplying hydrogen gas and a oxidant gas, a hydrogen gas passage 10 fo...

An exhaust gas processing device for a fuel cell is disclosed. In the exhaust gas processing device, hydrogen gas purged from the fuel cell is mixed with cathode exhaust gas from the fuel cell and dilutedprior to being discharged to an atmosphere. The exha...

A fuel cell assembly (50) having manifold means for providing fuel and air to, and removing spent fuel and air from, flow passageways across the anodes (16) and cathodes (18) in a fuel cell stack. The sizes and proportions of the supply (23',33') and retur...

An anode stream recirculation system for a fuel cell comprising an anode gas supply (60), a switch (62) and a regulating device (64) to properly control the amount of anode gas supply; a sensor (66) connected with the switch to detect the pressure of the a...
