Abstract:
1. A device for supplying a gaseous mixture containing hydrogen and carbon monoxide in a concentration not exceeding 100 ppm to a primary fuel cell supplied with air, comprising: a reformer configured to convert a fuel into a gaseous mixture containing carbon monoxide and hydrogen; a purification device configured to lower the carbon monoxide concentration of the gaseous mixture and connected to an inlet of an anode of the primary fuel cell; an auxiliary fuel cell, configured to be supplied with air and receive carbon monoxide produced by the reformer, and configured to convert part of chemical energy of the carbon monoxide to electrical energy; and a gas-permeation membrane configured to separate the hydrogen from other gases, and connected to the reformer, to the purification device, and to the auxiliary fuel cell, and mounted such that the hydrogen thus separated is passed into the purification device and the other gases, including the carbon monoxide, are passed into the auxiliary fuel cell.
