    • PROBLEM TO BE SOLVED: To provide an inexpensive electrolyte with comparatively simple synthesis, indicating high proton conductivity even in an absolute or low humidity environment, and to provide a fuel cell using the same. SOLUTION: The electrolyte includes anion including at least one center element comprising one type or more elements from B, Al, P, Sb and As, and at least one organic conjugation group bonded with the center element, cation, and a basic molecule capable of coordinating the cation. A ratio (=b/a) of the number of moles (b) of the anion with respect to the number of moles (a) of the group capable of coordinating the cation included in the basis molecule is less than 1/1. The fuel cell uses the electrolyte in an electrolyte membrane and/or a catalyst layer internal electrolyte. COPYRIGHT: (C)2010,JPO&INPIT
