Description

PEM fuel cells contain a proton-conducting membrane which separates two half-cells. They require no other electrolytes, and that means that they can function with almost no liquid. Due to the low voltage that an individual fuel cell supplies, many fuel cells are wired together to form a "stack". In experiment C4.4.7.1, the function of such a fuel cell stack is studied and various circuits are compared with one another.
