Porous Metal Tubular Support for Solid Oxide Fuel Cell Design

Abstract

A porous nickel tubular support of diam was successfully created by heat-treating a commercial nickel tube. The resulting tube contained uniform pores, whose diameters ranged from 0.5 to , depending on treatment temperature. The porous metal tube obtained is a promising candidate for support materials for microfuel cells or gas separation membranes because it has the necessary gas permeability and mechanical strength. It was also confirmed that a solid oxide fuel cell design employing the porous nickel tube as a supporting anode could be operated.
