Title:

ELECTROLYTE FOR FUEL CELL AND FUEL CELL

Document Type and Number:

WIPO Patent Application WO/2005/086266

Kind Code:

A1

Abstract:

Disclosed is an electrolyte for fuel cells which is composed of a room temperature molten salt containing an anion expressed as (HX)_yX^- (wherein X represents one of group 17 elements and y represents a positive real number). In particular, an onium salt formed together with a cation, namely EMI(HF)_2.3F is excellent in hydrogen transfer ability, and thus can be preferably used as an electrolyte for fuel cells.
