“…Further, the polarization losses on the anode side in the PEMFC found to be negligibly small [31]. There was a trial to build mathematically the model of the CCL for the phosphoric acid fuel cells (PAFC) [32] in order to analyze the voltage drop phenomena.…”

The influence of the sintering of electrocatalysts and decrease of the proton conductivity on the current-voltage performance in the HT-PEMFC was theoretically evaluated under the non-humid conditions at 150 °C, 170 °C and 190 °C. Decreasing rate of the proton conductivity was evaluated based on the tortuosity of the proton pass. The more the phosphoric acid was evaporated with a rise in temperature, the proton path found to become more tortuous and the proton conductivity was accordingly estimated to be decreased. A theoretical breakdown of the voltage drops indicated that the sintering of the electrocatalyst influenced on the voltage drop in earlier several hundreds of hours. The following voltage drop in the latter stage was caused mainly due to the decrease in the proton conductivity.

“…In the case of the PEMFC, polarization losses on the anode side, or the hydrogen electrode, are negligibly small [40]. Choudhury also used the mathematical model of the CCL to investigate the potential drop in the case of phosphoric acid fuel cells (PAFCs) [41]. Therefore, the 3D CCL model of the HT-PEMFC was constructed for the present study.…”

“…For instance, both the phosphoric acid FC (PAFC) and the molten carbonate FC (MCFC) have a liquid electrolyte, whereas a solid oxide FC (SOFC) has a solid, ceramic electrolyte [20]- [22]. A proton exchange or polymer electrolyte membrane FC (PEMFC) and a direct methanol FC (DMFC) may have the same solid polymer electrolyte, but the DMFC uses liquid methanol for fuel whereas the PEMFC uses gaseous hydrogen [23], [24].…”
