FUEL CELL AND ITS RELATED TECHNOLOGY. I. CORRELATION BETWEEN MAGNETIC SUSCEPTIBILITY AND CATALYTIC ACTIVITY OF ELECTRODE

Abstract

Magnetic susceptibility serves as good index for catalytic activity of the half cell electrode in a fuel cell. The theory of magnetism was outlined with a brief account of the molecular field theory of paramagnetism and domain theory of ferromagnetism. Contamination, notably oxygen, of the ferromagnetic film has a marked effect on the magnetic property. The control mechanism for the catalytic reaction at the electrode is postulated to involve chemisorption. For the measurement of magnetic susceptibility, three methods were proposed. The method finally adopted for the magnetic susceptibility measurement is a modified version of Gouy's method. The mechanical details and complete layout as well as theoretical analyses are fully described. (Author)
