摘要：

The proton activity of phosphoric acid and trifluoromethane sulfonic acid is determined at 150° and 90°C by electrochemical potential measurements. The transference number of ions required for the calculation of proton activity is determined by measuring the diffusion coefficients of ions using radiotracer techniques. The proton activity of TFMSA is determined to be higher than that of phosphoric acid at the temperature and concentration at which the acid fuel cell operates. © 1990, The Electrochemical Society, Inc.
