Patent ID: 7694550

Claim:
An apparatus for measuring the permeability of an anode of a solid oxide fuel cell, the apparatus comprising: a specimen container comprising: a can comprising a tunnel defined therein and a cavity in communication with the tunnel, wherein the anode can be disposed in the cavity such that at least a portion of a first side of the anode is sealed; and a cover comprising 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 and such that at least a portion of an opposite second side of the anode is sealed and wherein the can connects with the cover such that the anode is fully enclosed by the specimen container; an air reservoir in communication with the cover; and a recorder for measuring and recording 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.
