US 2009/0151430 A1 · Apparatus for measuring permeability rate of anode of solid oxide fuel cell

Abstract

An apparatus is disclosed for measuring the permeability of an anode of a solid oxide fuel cell. The apparatus includes a specimen container, an air reservoir and a recorder. The specimen container includes a can and a cover. The can includes a tunnel defined therein and a cavity in communication with the tunnel. The anode can be disposed in the cavity. The cover includes a tunnel defined therein and a bulger inserted in the cavity and pressed against the anode so that air can penetrate the anode and travel into the tunnel of the can from the tunnel of the cover. The air reservoir is in communication with the cover. The recorder measures and records the pressure and temperature of air in the air reservoir before and after the air is introduced into the specimen container from the air reservoir.
