A high-temperature solid polymer electrolyte fuel cell using H3PO4-doped polybenzimidazole (PBI) as proton-exchange membrane has been developed and tested. The influences of temperature (in a range between 130 and 170 °C), pressure (in a range between 1 and 3 bars) and air flow rate onto fuel cell performances have been studied. A maximum output power density of 200 mW·cm−2 has been obtained. The existence of an optimum air flow rate (expressed in oxygen stoichiometric ratio) has been put into evidence. It allows an increase of the fuel cell voltage from 250 mV up to ca. 400 mV at 0.4 A·cm−2. The results of the calculation of efficiency of PBI-based electrochemical power plant using the products of natural gas conversion as a fuel are presented.
