ANODE SUPPORTING BODY FOR SOLID OXIDE FUEL BATTERY, ANODE SUPPORTING TYPE HALF CELL, ANODE SUPPORTING TYPE SOLID OXIDE FUEL BATTERY SINGLE CELL, AND METHOD OF MANUFACTURING ANODE SUPPORTING TYPE HALF CELL

摘要

PROBLEM TO BE SOLVED: To provide an anode supporting body for a solid oxide fuel battery having a high porosity while maintaining sufficient mechanical strength, and to provide an anode supporting type solid oxide fuel battery single cell.SOLUTION: An anode supporting body for a solid oxide fuel battery comprises: a paper-like porous supporting base substance configured by molding an ion conductivity oxide fiber in a nonwoven fabric state; and an anode active layer configured by electrode catalyst particles and ion conductivity oxide particles. At least a part of the anode active layer is formed inside the paper-like porous supporting base substance. With respect to an anode supporting type solid oxide fuel battery single cell having the anode supporting body, a pore size and a porosity (a void ratio) of the anode supporting body is extremely large, and not only a three-phase interface where electrode reaction occurs is expanded three-dimensionally on a network configured by the ion conductivity oxide fiber, but also a thickness of the three-phase interface expanded in the network (a thickness from the ion conductivity oxide surface) can be kept thin. Thus, excellent power generation performance is exhibited.
