In a PEM, the electrolyte is a polymer membrane, called the proton exchange membrane.

Question

Quizplus · Accepted Answer

In a Proton Exchange Membrane (PEM) fuel cell, the electrolyte is indeed a polymer membrane, specifically designed to conduct protons while being impermeable to gases such as hydrogen and oxygen. This membrane is crucial for the cell's operation, allowing only protons to pass through it from the anode to the cathode, while electrons travel through an external circuit to generate electricity.
