| Zusammenfassung: | The present invention provides an ion conductive layer for a fuel cell, through which ions generated by the oxidation reaction of liquid fuel pass before reaching a membrane in a fuel cell. The ion conductive layer for a fuel cell includes: a substrate into which the liquid fuel and an electrolyte are introduced; and pores formed in the substrate, wherein the pores are formed to have a porosity of 10 % or more, thereby suppressing a crossover phenomenon in which the liquid fuel passes through the membrane.
