<P>PROBLEM TO BE SOLVED: To provide a fuel battery capable of increasing an amount of water supplied to an anode (a fuel electrode) and suppressing the deterioration of the diffusion of an oxidizing gas on a cathode catalyst layer and obtaining a high output. <P>SOLUTION: The fuel battery 1 comprises an anode (a fuel electrode) 13, a cathode (an air electrode) 16, a fuel battery cell 10 having an electrolyte membrane 17 sandwiched by the anode and the cathode, a moisturizing layer 50 arranged by being laminated on the cathode (air electrode) 16, and a surface cover 60 arranged by being laminated on the moisturizing layer 50 and having an air inlet 61. The cathode catalyst layer 14 of the cathode (air electrode) 16 has a first catalyst layer 14a located so as to correspond to the air inlet 61 of the surface cover 60, and a second catalyst layer 14b forming a section excluding the first catalyst layer 14a. <P>COPYRIGHT: (C)2010,JPO&INPIT |
