$H_2O_2$ can be prepared by successive reactions

Question

$2NH_4HSO_4\rightarrow H_2+(NH_4)_2S_2O_8$

$(NH_4)_2S_2O_8+2H_2O\rightarrow 2NH_4HSO_4+H_2O_2$.

The first is an electrolytic reaction and the second a steam distillation.What current needs to be passed in first reaction to produced enough intermediate to yield 100gm of pure $H_2O_2$ per hour? ( Assume 50% current efficiency )
