how does internal resistance of a cell vary with temperature? pls answer me.

Internal resistance of a cell is defined as the resistance offered by the electrolyte and electrodes of a cell when the electric current flows through it.On increasing temperature , in electrolytes, there is increase in thermally generated electrons over the existing ions, so the internal resistance will decrease with the increase of temperature and increase with the decrease of temperature.

if we think in terms of solutions, the number of ions increases on heating,i.e. rise in temperature,which means increased conductance.So resistance decreases.
