electrolysis - Question and answers

I'm trying to set up a small-scale electrolysis system for water purification, but the hydrogen production is much lower than expected. What could be causing this inefficiency and how can I optimize it?

Chemical Effect of Electric Current performance-optimization electrolysis

I'm using a simple setup with two stainless steel electrodes in a container of tap water, powered by a 12V DC power supply. The electrodes are spaced about 5 cm apart, and I'm measuring the gas output over 30 minutes. I've checked for leaks and ensured the connections are secure, but the hydrogen yield is only about half of what online calculators predict based on current flow. What am I missing?
