Measurement of Proton Concentration in PEM by Hall Effect
A method based on Hall effect is applied to measure proton concentration in polymer electrolyte membrane. Although Hall effect is present in any kind of charge carriers, due to the fact that electrons are the charge carriers in any electronic device, only Hall voltage of electron systems can be measured. In this paper we show how Hall effect induces voltage on proton system in polymer electrolyte membrane (PEM) of fuel cell of the same magnitude as in the electron system. In this way it is possible to determine essential microscopic properties of the proton system in the polymer electrolyte membrane, such as proton concentration and mobility.
