Question

ting water molecules with electricity to produce
hydrogen and oxygen) is the opposite of the reaction
that occurs in a hydrogen fuel cell. answer in a couple of sentences

Answer 1

In hydrolysis, water molecules are broken down into hydrogen and oxygen through the use of electricity. This process requires energy input to separate the molecules. In a hydrogen fuel cell, the opposite reaction occurs where hydrogen and oxygen combine to produce water and release energy, which is used to power the cell.
