Improving stability of chloralkaline high-temperature PBI-PEMFCs
This work focuses on the production of electricity using chloralkaline high temperature PEM fuel cells (HT-PEMFC) comparing, within the range 120–180 °C, the performance of a cell equipped with a cathode containing a novel Ru/Pt catalyst manufactured at mild temperature conditions with another cell...

| Sumario: | This work focuses on the production of electricity using chloralkaline high temperature PEM fuel cells (HT-PEMFC) comparing, within the range 120–180 °C, the performance of a cell equipped with a cathode containing a novel Ru/Pt catalyst manufactured at mild temperature conditions with another cell which contains a conventional Ru based catalyst (Ru0.75Pt0.25O2). Performance of the cell equipped with the conventional electrode at 120 °C is much better, but this situation reverses at higher operation temperatures, where the novel catalyst outperforms the conventional Ru0.75Pt0.25O2 in terms of production of electricity. In addition, the new catalyst allows to operate even at 180 °C, temperature at which the cell equipped with the conventional electrode is completely deteriorated. Results pointed out that materials are the bottleneck for the chloralkaline HT-PEMFC technology but opens the window for the search of new materials that help to improve their future development. |
