<P>PROBLEM TO BE SOLVED: To provide a fuel cell allowing a fuel cell system to be downsized. <P>SOLUTION: In this fuel cell, four fuel battery cells 10, a fuel feed passage to the fuel battery cells 10, and micro valves 5a and 5b regulating the supplied amount of liquid fuel passing the individual fuel introduction parts 3a and 3b of the fuel feed passage are integrated in the same substrate. The substrate comprises a holding body 16 for holding four fuel battery cells 10, a gas-liquid separating membrane 2, a fuel pole side substrate 3, and an air pole side substrate 4. The fuel battery cell 10 comprises an ionic conduction membrane 11 held by a fuel pole 12 and an air pole 13. The mixed fluid of methanol and water is fed to the fuel pole 12 and air is fed to the air pole 13 through the permeable holes 4a in the air pole side substrate 4. Carbon dioxide produced at the fuel poles 12 of the fuel battery cells 10 is discharged to the outside through the air-liquid separating membrane 2 and discharge holes 31 in the fuel pole side substrate 3. <P>COPYRIGHT: (C)2004,JPO |
