ABSTRACT:
According to one embodiment, a direct methanol fuel cell includes an anode having a current collector and a catalyst layer formed on the current collector, a cathode having a current collector and a catalyst layer formed on the current collector, and an electrolyte membrane placed between the catalyst layers of the anode and the cathode. The anode-side catalyst layer includes a catalyst and a sheet-like organic compound consisting of a plurality of molecules having an aliphatic cyclic skeleton in which two carbon atoms are bonded to a cationic functional group and an anionic functional group, respectively. The sheet-like organic compound has a layered branch structure in which the molecules are layered by bonding different ions of the aliphatic cyclic skeleton to one another so that the molecules are displaced from one another, and a plurality of units each having the layered branch structure are present in the catalyst layer.
