Abstract
A solid oxide fuel cell including a closed cylindrical solid oxide fuel cell body including a solid electrolyte, an air electrode and a fuel electrode, a gas supply tube for supplying an oxidizing gas or a fuel gas, partition members arranged between the fuel cell body and the gas supply tube for dividing the hollow space into a plurality of gas flowing passages, a sealing member, at least one exhaust port formed in each of the gas flowing passages, and a support means for holding the opening end side of the fuel cell body.
Claims8
A solid oxide fuel cell comprising:
- a cylindrical solid oxide fuel cell body having an open end and an opposed, closed end and at least provided with a solid electrolyte, an air electrode and a fuel electrode;
- a gas supply tube for supplying an oxidizing gas or a fuel gas to a hollow space of the solid oxide fuel cell body;
- partition members arranged between an inner peripheral surface of the solid oxide fuel cell body and an outer peripheral surface of the gas supply tube and dividing the hollow space of the solid oxide fuel cell body into a plurality of gas flowing passages;
- a sealing member closing said open end of the solid oxide fuel cell body;
- at least one exhaust port formed in each of the gas flowing passages for discharging the oxidizing gas or fuel gas flowing in the gas flowing passages to an exhaust gas chamber;
- and
- support means for holding an outer peripheral surface of the solid oxide fuel cell at said open end thereof.
