There are provided a fuel cell having stable and good power generation characteristics and good safety, a fuel cell system including the fuel cell and an electronic device equipped with the fuel cell. The fuel cell includes at least an electrolyte membrane, an anode formed on one surface of the electrolyte membrane, a cathode formed on the other surface of the electrolyte membrane, a liquid fuel chamber for supplying a liquid fuel to the anode, and a separating layer formed between the anode and the liquid fuel chamber. The separating layer and/or the anode has an exhaust passage that is continuously formed in an in-plane direction to discharge exhaust gas generated at the anode. The separating layer allows the liquid fuel to pass from the liquid fuel chamber to the anode and blocks the movement of gas from the anode to the liquid fuel chamber.

A catalyst layer for a fuel cell membrane electrode assembly includes a plurality of agglomerates, adjacent ones of the plurality of agglomerates contacting with each other with pores provided between said adjacent ones of the plurality of agglomerates, each of the plurality of agglomerates being formed by packing a plurality of catalysts each consisting of noble metal fine particles supported on a fiber-like support material, adjacent ones of the plurality of catalysts contacting with each other with pores provided between said adjacent ones of the plurality of catalysts, and each of the plurality of catalysts contacting with a plurality of catalysts other than said each catalyst at a plurality of contact points. This allows providing a catalyst layer, a fuel cell membrane electrode assembly, and a fuel cell, each of which has compact size and excellent power generation performance, and a method for producing the same.
