Schematics for a H2SO4/H2O2 electrolytic cell?

I was wondering how that'd actually work, and whether you can get a reasonable yield of H2O2 at lab scale out of it.

well 3 problems
H2O2 decomposes when rough catalytic surfaces are present so even a little dirt dust and or anode sludge will make this reaction hard.
High temperatures also prevent fre H2O2 in solution from occuring.
H2SO4 as electrolyte with platinum anode present wont yield H2O2 but a mixture of peroxymono sulfuric acid and peroxy di sulfuric acid and some deadly ozone gas.
Cody's lab made H2O2 by a reaction of anthraquinone with hydrogen using a palladium catalyst then subsequent reaction of that solution to oxygen which liberates your peroxide.

Well, I meant peroxomonosulfuric acid in this case, with the H2O2 being the desired final product...
