•SeO2 inhibited the H2 evolution and indirectly improved the Mn deposition.•High current density led to Mn2+ mass transfer limitation and H2 evolution speeding up.•High Mn2+ concentration improved Mn deposition and inhibited H2 evolution.•Stainless steel had smaller H2 overpotential and faster H2 ev...
