| titleOfInvention | IONIC LIQUIDS AND IONIC LIQUID ACIDS WITH HIGH-TEMPERATURE STABILITY FOR FUEL CELLS AND OTHER HIGH-TEMPERATURE APPLICATIONS, MANUFACTURING METHOD AND CELL THEREWITH |
| abstract | Disclosed are developments in high temperature fuel cells including ionic liquids with high temperature stability and the storage of inorganic acids as di-anion salts of low volatility. The formation of ionically conducting liquids of this type having conductivities of unprecedented magnitude for non-aqueous systems is described. The stability of the di-anion configuration is shown to play a role in the high performance of the non-corrosive proton-transfer ionic liquids as high temperature fuel cell electrolytes. Performance of simple H2(g)electrolyte/O2(g) fuel cells with the new electrolytes is described. Superior performance both at ambient temperature and temperatures up to and above 200°C are achieved. Both neutral proton transfer salts and the acid salts with HSO-4 anions, give good results, the bisulphate case being particularly good at low temperatures and very high temperatures. The performance of all electrolytes is improved by the addition of a small amount of involatile base of pKa value intermediate between those of the acid and base that make the bulk electrolyte. The preferred case is the imidazole-doped ethylammonium hydrogensulfate which yields behavior superior in all respects to that of the industry standard phosphoric acid electrolyte. |
