•First time CRM-free cathode AEMFC evaluated at temperatures > 100 °C•At 105 °C, the AEM reaches an OH‾ conductivity of 201 mS cm−1•Highest performing CRM-free cathode HT-AEMFC – 1.14 W cm−2 peak power density We present a first high-temperature anion-exchange membrane fuel cell (HT-AEMFC, operating at 105 °C) based on a critical raw material (CRM)-free cathode catalyst; at the same temperature, the anion-exchange membrane (AEM) has an ex-situ high hydroxide conductivity value of 201 mS cm−1. Our HT-AEMFC, containing a highly active nitrogen-doped carbon (N-doped-C) cathode catalyst, also features low polarization resistances, high catalytic activity and stability with retention of 81% of the catalyst layer capacitance after an initial 10 h longevity test, and 1.14 W cm−2. This is one of the highest power densities reported for a CRM-free AEMFC cathode. This work shows the potential of the new field of HT-AEMFCs, opening opportunities for developing and using novel CRM-free catalysts; highly active at these high operating temperatures.
