There is provided a fuel cell having excellent portability and transportability and exhibiting superior power generation efficiency for which it is possible to use a liquid or solid fuel, which has higher energy density than a gaseous fuel. A fuel cell includes an electrolyte ( 1 ), an anode ( 2 ) and a cathode ( 3 ) that are disposed so as to sandwich the electrolyte ( 1 ), and further includes a fuel supply portion that supplies a fuel to the anode ( 2 ), an oxidant supply portion that supplies an oxidant containing oxygen to the cathode ( 3 ), and a cell heating portion that heats the fuel cell, and the electrolyte ( 1 ) is made of a solid oxide, and the fuel is a liquid or solid at room temperature and normal pressure.
