Abstract
Disclosed is an ion conducting layer for fuel cells, through which ions generated by oxidation of liquid fuel pass before the ions reach a membrane in a fuel cell. The ion conducting layer includes: a substrate into which the liquid fuel and an electrolyte are introduced; and pores formed in the substrate, wherein the pores are formed at a porosity of 10% or more in the substrate to suppress a crossover phenomenon in which the liquid fuel passes through the membrane.
