(57) [Problem] To provide a fuel cell capable of smoothly supplying liquid fuel to a negative electrode and exhibiting stable output as a liquid supply type fuel cell. SOLUTION: As a liquid supply type fuel cell, a catalyst capable of electrochemically reducing oxygen on a positive electrode, a catalyst capable of electrochemically oxidizing liquid fuel on a negative electrode, In each of the fuel cells used, the anode-side diffusion layer 4 carrying the anode catalyst layer 9 is made of a hydrophilic carbonized porous carbon material, particularly carbon paper or carbon cloth that has been subjected to hydrophilic treatment. A fuel cell comprising: |
