Abstract

Structure of the disclosed fuel cell includes porous anodal thin film, compact solid electrolyte film, reaction barrier layer, active layer of cathode, contact layer of cathode, supporter of porous stainless steel, reforming catalyst. Porous anodal thin film, compact solid electrolyte, reaction barrier layer, active layer of cathode, and contact layer of cathode are tight connected in sequence from bottom-up so as to constitute single cell. Supporter of porous stainless steel of carrying reforming catalyst is located at underside porous anodal thin film. The invention raises performances of structural stability, electrocatalysis capability of anode, heat evenness of fuel cell so as to increase service life. Structure of system is more compact and possesses higher efficiency. The invention possesses very important meaning for solving key issue faced by solid oxide fuel cell for applying to power generation system.

Description

technical field [0001] The invention relates to a battery in the field of fuel cell technology, in particular to a structure of a porous metal-supported low-temperature solid oxide fuel cell. Background technique [0002] The main obstacles to the commercial development of solid oxide fuel cells are the battery stack system life and system price, and the operating temperature of solid oxide fuel cells is an important factor determining these two aspects. At present, many research and development units in the world are actively developing medium-temperature solid oxide fuel cells, that is, reducing the conventional operating temperature of about 950°C to 700-800°C. Among them, Ni-YSZ (YSZ: yttrium-stabilized zirconia) anode-supported medium-temperature solid oxide fuel cell has received extensive attention in the world in recent years. Its operating temperature is 700-800 ° C, and its excellent cell stack performance has also been reported. , some research and development un...
