Abstract
A fuel cell system includes a fuel cell module, auxiliary equipment, a power converter, and a casing containing the fuel cell module, the auxiliary equipment, and the power converter. The casing has a plurality of surfaces including one detachable maintenance surface. Only the maintenance surface has an air intake port for taking an oxygen-containing gas into the casing, an air exhaust port for discharging an exhaust gas discharged from the fuel cell module, to the outside of the casing, and a ventilation inlet port and a ventilation outlet port for ventilation of an inside of the casing by air.
Claims6
A fuel cell system comprising:
- a fuel cell module configured to generate electric power by electrochemical reactions of a fuel gas and an oxygen-containing gas;
- auxiliary equipment as a peripheral device of the fuel cell module;
- a power converter configured to convert direct-current electric power generated in the fuel cell module into an electric power according to a power supply output specification;
- and
- a casing housing the fuel cell module, the auxiliary equipment, and the power converter,
- wherein
- the casing has a plurality of surfaces, the surfaces including one maintenance surface, the maintenance surface being one of detachable or openable/closable;
- only the maintenance surface has:
- an air intake port configured to take the oxygen-containing gas into the casing;
- an air exhaust port configured to discharge an exhaust gas discharged from the fuel cell module, to outside of the casing;
- and
- a ventilation inlet port and a ventilation outlet port for ventilation of an inside of the casing by air;
- the casing contains therein:
- a power converter chamber communicating with the air intake port and containing the power converter;
- an air intake flow channel configured to allow the oxygen-containing gas introduced from the air intake port into the casing to flow along the power converter provided in the power converter chamber;
- and
- a fuel cell module chamber containing the fuel cell module;
- the power converter chamber is divided by a guide wall plate into:
- a first area that is provided with the air intake port and extends between the maintenance surface and a back surface of the casing that is opposite to the maintenance surface, and
- a second area that extends between the maintenance surface and the back surface of the casing,
- an oxygen-containing gas supply unit is provided in the second area inside the maintenance surface, the oxygen-containing gas supply unit being configured to supply the oxygen-containing gas that has flowed through the air intake flow channel, to an oxygen-containing gas system flow channel of the fuel cell module;
- the oxygen-containing gas supply unit has a chemical filter;
- and
- the power converter chamber and the fuel cell module chamber are separated by a partition plate.
