Define the following terms:(i) Fuel cell(ii) Limiting molar conductivity(Λ°m)

Fuel cell:-A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction.
Limiting Molar Conductivity:-Molar conductivity is defined as the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte, and so measures the efficiency with which a given electrolyte conducts electricity in solution. It is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution.
