Abstract
The invention provides a reference electrode including a liquid electrolyte containing water, a water soluble organic compound with molecular size and boiling point are both greater than water, and an ionic salt; a solid crystal of the ionic salt in the liquid electrolyte; a metal/metal salt complex layer in contact with the liquid electrolyte; an leading wire connected to the metal/metal salt complex layer; an insulation case for containing the liquid electrolyte; and a nano-porous junction material embedded in the insulation case for contacting the liquid electrolyte, wherein a pore size of the nano-porous junction material is greater than a cation diameter of the ionic salt but smaller than a molecular length of the water soluble organic compound. The solid crystal of the ionic salt is the sediment of part of the ionic salt because the amount of the ionic salt is more than its solubility in the liquid electrolyte.
