Electrochemical Hydrogen Concentrator for Phosphoric Acid Fuel Cells.

Abstract

The production of high purity hydrogen for use in phosphoric acid fuel cell from heavily contaminated reformed diesel fuel gas using an electrochemical device has been demonstrated. The electrochemical hydrogen separator (EHS) is based on current PAFC technology. Hydrogen is removed from the contaminated gas stream by oxidation to hydrogen ions at a gas diffusion cathode. An anode catalyst with excellent tolerance to high levels of CO and H2S contaminants has been developed. The use of this anode catalyst would allow the EHS device to produce pure hydrogen with minimal voltage impact on the overall PAFC power output. Reduction in size and weight of the PAFC power plant is also indicated through reduced load on fuel processing components. Keywords: Hydrogen, Phosphoric acid, Fuel cell, Gas separation, Electrochemical cell, Reformed diesel.
