SOLID OXIDE FUEL CELL

摘要

PURPOSE: A solid oxide fuel cell is provided to obtain electrical reliability between an electrode and an electrical connection unit, thereby increasing the rigidity and durability of a unit cell. CONSTITUTION: A solid oxide fuel cell(100) comprises a tubular first electrode(10); an electrolyte(20) laminated on the outer side of the first electrode; a second electrode(30) laminated on the outer side of the electrolyte; and at least one elastic member providing elasticity in the diameter direction. At least one of the first and second electrodes is an air electrode and the other is a fuel electrode. The solid oxide fuel cell additionally includes the first electrode and the first electrode current collector(40) inserted into the first electrode and elastic member.
