When someone gets electrocuted does some of the water in their bodies split?

Into h2 (hydrogen gas) and oxygen gas?

Sorry if that came off as morbid. But humans and animals have positive charged membranes and negative charged ones, which came into my head as like electrodes.

Just need a current, eg. lightning strike, touching a live wire, etc
I tried researching this but I found no conclusive answer.

The electric chair is perhaps the main source in question.

No, not really. Phospholipids have positively and negatively charged domains. Phospholipid bilayers (ie. membranes) have a membrane potential as a result of the passage of ions across the membrane. But I don’t think it’s correct to say that there are "positively charged" and "negatively charged" membranes.
