This sheet is designed to
complement Water Electrolysis & Hydrogen Electrolysers
fact sheet. It provides questions for students to
answer about the electrolysis of water, including the ratio
of gases produced and three main types of electrolyser cells
used to produce hydrogen from the electrolysis of
water.
