High-temperature polymer electrolyte fuel cell HT-PEFC

Fig. 10 Comparison of voltage losses of low- and high-temperature fuel cells at 0.2 A cm (a) and 0.8 A cm (b). Experimental conditions for the low-temperature polymer electrolyte fuel cell (LT-PEFC) were as follows Pt/Ketjenblack, 0.4mgp cm , 80°C, ISOkPa, 66% relative humidity (inlet), residence time 1.3 s. Experimental conditions for the high-temperatmc polymer electrolyte fuel cell (HT-PEFC) were as follows platinum alloyA ulcan XC72, 0.7mgp, an 160°C, lOOkPa, dry gases, residence time 2.5 s. (The data for the LT-PEFC were extracted from Yu et al. 2006)...
