Fuel cell is better than battery due to its lower cost

The oxidized form of an element is a good oxidizing agent

The inactive nature of the fuel cell electrodes is the main difference between the fuel cells and batteries

Redox reactions happen in both fuel cells and batteries

Electrochemical series is an arrangement of the oxidation potential of the elements at standard conditions

Galvanic reactions are spontaneous reactions that happens in both fuel cells and batteries

According to Faraday's law $($first and second$),$ the amount of material deposited $($precipitated$)$ or evolved $($gas$)$ is dependent on the amount of electricity used and the molar $()$ mass of the materials

Nafion is considered as a good membrane in PEMFC due to its high electrical conductivity

Fuel cell Stack is an arrangement of single cells in series to increase the power

The actual cell voltage and theoretical cell voltage of a fuel cell are same $C$
