Resistance of a conductivity cell filled with $0\cdot1\text{ mol L}^{-1}\text{ KCl}$ solution is $100\ \Omega$. If the resistance of the same cell when filled with $0\cdot02\text{ mol L}^{-1}\text{ KCl}$ solution is $520\ \Omega$, calculate the conductivity and molar conductivity of $0\cdot02\text{ mol L}^{-1}\text{ KCl}$ solution. The conductivity of $0\cdot1\text{ mol L}^{-1}\text{ KCl}$ solution is $1\cdot29 \times 10^{-2}\ \Omega^{-1}\text{cm}^{-1}$.

Define the following terms:
(1) Limiting molar conductivity.
(2) Fuel cell.
