Data for "Feasibility of ultra-low Pt loading electrodes for high temperature proton exchange membrane fuel cells based in phosphoric acid-doped membrane"

Data corresponding to the polarization and power density curves of PBI-based MEAs with ultra-low Pt loading electrodes (0.025 - 0.1 mg_Ptcm^-2). The tests were performed in HT-PEMFCs under ambient pressure, H₂/Air and 180ºC. Data comprise the optimization of the ultra-low Pt loading of the anode electrode, the optimum catalyst (in terms of Pt/C wt.% concentration), the effect of the binder content (PTFE) of the electrodes and the influence of the deposition method (ultrasonic-spraying, electrospraying and airbrushing) on the performance of ultra-low Pt loaded electrodes for HT-PEMFCs.
