Abstract:
1. A direct methanol fuel cell comprising: an anode to which an aqueous methanol solution is fed as a fuel, the anode having a current collector and a catalyst layer formed on the current collector; a cathode to which an oxidant is fed, the cathode having a current collector and a catalyst layer formed on the current collector; and an electrolyte membrane placed between the catalyst layer of the anode and the catalyst layer of the cathode, wherein at least the anode catalyst layer of the anode and cathode catalyst layers comprises a catalyst and organic compounds consisting of a plurality of molecules represented by formula (I) below, which has a cationic functional group and an anionic functional group, each of the organic compounds has a layered branch structure in which molecules of formula (I) are layered by bonding different ions of each molecule to one another so that the molecules are displaced from one another, where R 1 represents an aromatic functional group having the anionic functional group bonded thereto, and n represents an integer of 1 to 40.
