    • This invention provides a fuel cell (A) that can prevent the loss of a liquid fuel caused by crossover and can develop high output and high energy density utilizing a high-concentration liquid fuel, and is suitable for power supplies, for example, in portable telephones. The fuel cell comprises at least an air electrode-side current collecting layer (10), an air electrode catalyst layer (11), a polymer electrolyte membrane (12), a fuel electrode catalyst layer (13), and a fuel electrode-side current collecting layer (14). A porous layer (20) formed of a porous material is provided on the liquid fuel side of the fuel electrode-side current collecting layer (14). The porous layer (20) is constructed so that the air permeation (value based on void tower) at a pressure difference of 100 kPa is 10 cm/s to 5000 cm/s. The porous layer (20) functions as a medium for diffusion of a fuel into the fuel electrode catalyst layer and as a resistor for discharge of gases comprised of carbon dioxide as an electrode reaction product, water vapor and vapor of the liquid fuel during the progress of the electrode reaction. Further, during the progress of an electrode reaction, the interface of the gases is formed in the porous layer or on the surface of the porous layer to form a layer of gases between the fuel electrode catalyst layer (13) and the porous layer (20). ® KIPO & WIPO 2009
