Paper-like catalyst for reforming hydrocarbons, paper-like catalyst array, and solid oxide fuel cell having paper-like catalyst or paper-like catalyst array

摘要

Uses a paper-like catalyst that has high reforming catalyst activity, can efficiently reform hydrocarbon gas, and does not easily destroy the catalyst structure due to thermal shock, or blockage or destruction of the catalyst gap. An internal reforming type solid oxide fuel cell was provided. The paper-like catalyst of the present invention comprises a paper-like porous carrier formed by molding inorganic fibers into a paper-like shape, and a metal catalyst having a reforming activity for hydrocarbons dispersed and supported on the surface of the paper-like porous carrier. In addition, at least part of the inorganic fibers constituting the paper-like porous carrier are ion conductive oxide fibers, have high hydrocarbon reforming activity, are resistant to thermal stress destruction, and are molded into a predetermined size and shape Is easy and the degree of freedom when arranging the catalyst is high. The internal reforming solid oxide fuel cell using the paper-like catalyst of the present invention as a hydrocarbon reforming catalyst can suppress deterioration due to thermal stress breakdown and carbon deposition, and thus generates power more stably. be able to.
