Subject: hydrogen peroxide

How does one produce H202 electrochemically? I know of the reaction 
K2SO4 + H20 gives K2SO3 + H202. But how is this implemented in 
practice? Does industry produce H202 in this way? Or are there other 
ways? I need this for a student's project: we're not going to actually 
produce it, but the student's need to be able to design a production 
process (a factory, that is) and think about the safety measures 
involved for peroxides and in electrochemistry. Would you also have 
some useful references for me, following the earlier discussion on how 
to make H2O2? Thanks
