#DanishPowerSystems sets new record with degradation rate in high-temperature polymer fuel cells #HTPEMFC

Danish Power Systems sets new record with degradation rate in high-temperature polymer fuel cells 25 September 2017 The clean technology company Danish Power Systems (DPS), with partners at the Technical University of Denmark (DTU) and the University of Chemistry and Technology in Prague, Czech Republic, reports the best operating stability for high-temperature polymer fuel cells (HTPEMFC) yet. In a 9,000-hour long test at 160 ˚C under constant load, the DPS cell exhibited a degradation rate of 0.5 μV h−1 —equivalent to degradation of 0.00008% per hour—compared to 2.6 μV h−1 for a reference membrane. For the full test period of 13,000 h, the average voltage decay rate was about 1.4 and 4.6 μV h−1 for cells equipped with cross-linked and linear polybenzimidazole membranes, respectively. Results are published in the Journal of Power Sources . Danish Power Systems manufacture...
