FUEL CELL, METHOD FOR PRODUCING ELECTRODE CATALYST LAYER FORFUEL CELL, AND METHOD FOR OPERATING FUEL CELL

摘要

Disclosed is a fuel cell wherein a complex-forming compound which is capable of forming a complex with hydrogen peroxide is dispersed and added in a membrane-electrode assembly. As the complex-forming compound, Ti(SO4)2 is preferable. In this fuel cell, harmful hydrogen peroxide generated during operation of the fuel cell can be removed from the cell, thereby suppressing deterioration of the electrolyte membrane or the electrolyte in the electrod e catalyst layer caused by hydrogen peroxide. Consequently, the fuel cell is improved in durability.
