Achievement of a novel organometallic electrocatalyst based on nickel and poly para-aminophenol with excellent oxygen reduction reaction activity: Promoting the commercialization of low temperature fuel cells

•Ni nanoparticles in new mesoporous poly para-aminophenol (Ni/PPAP) is exploited.•Ni/PPAP is used as a new organometallic electrocatalyst for ORR in acidic media.•Adding carbon to the Ni/PPAP increases the rate of ORR.•Carbon with 10% of Ni/PPAP exhibits fast kinetics than platinium catalysts.•Using 10% of Ni/PPAP in electrode shows a remarkable oxygen diffusion.•The fabricated electrode with 10% of Ni/PPAP displays long term performance.
