<p><P>PROBLEM TO BE SOLVED: To provide a fuel battery which can suppress the deterioration of an anode electrode by using a low-cost means while removing a produced carbon dioxide; and to provide a fuel battery system having the fuel battery and an electronic appliance. <P>SOLUTION: In the fuel battery, a groove 22 (a first groove 221 and a second groove 222) is disposed in a surface opposed to an anode electrode of an anode-side planar member 20. The first groove 221 is formed in the region opposed to the anode electrode, and the second groove 222 is formed up to an exit 222A of the side surface of the anode-side planar member 20 by branching off from the first groove 221. The carbon dioxide produced by the electric chemical reaction of a fuel F is exhausted through the groove 22. Since the groove 22 does not pierce the anode-side planar member 20, the unused fuel F is absolutely transported through the surface of the anode electrode, so that the fuel F is consumed enough and is prevented from being exhausted to the outside of the fuel battery system. Also, by providing a valve 23 in the groove 22, the forced entry of air into a fuel vaporizing room 42 is suppressed during power generation stop. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
