Phosphoric acid fuel cell technology

Abstract

The overall aim was the development of phosphoric acid fuel cells with the emphasis on finding alternative electrolytes, and on the optimization of manufacture of high surface area gas-diffusion electrodes and electrolyte retaining matrices. An introduction to fuel cells is given, literature on phosphoric acid fuel cells is reviewed and the experimental phosphoric acid fuel cell developed is described. The cell heating devices, fuel gas flow system and cell test equipment are outlined. Preparation of the gas-diffusion electrodes and the electrolyte matrices are explained. The electrochemical charateristics of the modified electrolytes and the fuel cell performance when the modified electrolytes were used are described in addition to the specific conductivity measurements of some of the modified electrolytes. A conclusion is that the improved cell performance with the modified electrolytes is not due to any increase of the conductivity of the modified electrolytes. Conductivity measurements of the CF{sub 3}SO{sub 3}H-H{sub 3}PO{sub 4}-H{sub 2}O mixtures of concentration and temperature are presented. (AB) (72 refs.).
