Title:
PROTON CONDUCTIVE MATERIAL, PROCESS FOR PRODUCING THE SAME, HYDROGEN CONCENTRATION CELL, HYDROGEN SENSOR AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2007/060748
Kind Code:
A1
Abstract:
A proton conductive material that can operate over a low temperature range to
a middle temperature range, being produced easily at low cost; a process for producing
the same; and, having the proton conductive material mounted thereon, a hydrogen
concentration cell, hydrogen sensor and fuel cell. There is provided a proton
conductive material characterized by containing calcium, sulfur and hydrogen
elements and exhibiting a proton conductivity of 10-6 S/cm or higher
at room temperature. The proton conductive material can contain, in terms of
oxide, 10 to 45 wt.% of CaO, 15 to 60 wt.% of SO3 and 5 to 55 wt.% of H2O.
Further, 0.1 to 50 wt.% of P2O5 can be contained.
