Abstract
Provided is a fuel cell including a container having at least two openings, a power generating unit contained in the container, the power generating unit having a membrane electrode assembly, an anode and a cathode channel plates, and a fan to supply oxygen into the membrane electrode assembly from one of the openings of the container. The cathode channel plate has a clearance against the container, and the cathode channel plate has the openings communicating with a space formed between the fan and the membrane electrode assembly on the face different from the opposite face, and the clearance.

A fuel cell comprising:
- a container including at least two openings;
- a power generating unit contained in the container, the power generating unit including a membrane electrode assembly, an anode channel plate and a cathode channel plate;
- and
- a fan to supply oxygen into the membrane electrode assembly from one of the openings of the container, wherein the cathode channel plate has a clearance against the container, and
- the openings of the container communicate, via the clearance, with a space disposed between the cathode channel plate and the membrane electrode assembly, the space being adjacent to a face of the membrane electrode assembly different from a face of the membrane electrode assembly opposing the fan.
A fuel cell system comprising:
- a container including at least two openings;
- a power generating unit contained in the container, the power generating unit including a membrane electrode assembly, an anode channel plate and a cathode channel plate;
- a fan to supply oxygen into the membrane electrode assembly from one of the openings of the container;
- a fuel cartridge which stores a fuel;
- fuel supply means for supplying the fuel to the power generating unit from the fuel cartridge;
- and
- a circulation line which circulates the fuel in the power generating unit, wherein
- the cathode channel plate has a clearance against the container, and
- the openings of the container communicate, via the clearance, with a space disposed between the cathode channel plate and the membrane electrode assembly, the space being adjacent to a face of the membrane electrode assembly different from a face of the membrane electrode assembly opposing the fan.
