A liquid fuel cell includes a positive electrode ( 8 ) for reducing oxygen, a negative electrode ( 9 ) for oxidizing fuel, a solid electrolyte ( 10 ) placed between the positive electrode ( 8 ) and the negative electrode ( 9 ), and liquid fuel ( 4 ), wherein the positive electrode ( 8 ) and the negative electrode ( 9 ) respectively include catalyst layers ( 8 b), ( 9 b) with a thickness of 20 mum or more, at least one of the respective catalyst layers ( 8 b), ( 9 b) has a pore with a pore diameter in a range of 0.3 mum to 2.0 mum, and a pore volume of the pore is 4% or more with respect to a total pore volume. Because of this configuration, a liquid fuel cell with a high output density can be provided in which the pore configuration in the catalyst layer is optimized, and catalyst performance is exhibited sufficiently. |
