Abstract
Official abstract text for this publication.
A proton conductor is in contact with a catalyst containing platinum. The proton conductor includes a cationic organic molecule, a metal ion, and an oxoacid anion. A protic ionic liquid containing the cationic organic molecule and the oxoacid anion is coordinated to the metal ion to form a coordination polymer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A proton conductor in contact with a catalyst containing platinum, the proton conductor comprising: a cationic organic molecule; a metal ion; and an oxoacid anion, wherein a protic ionic liquid containing the cationic organic molecule and the oxoacid anion is coordinated to the metal ion to form a coordination polymer. 2 . The proton conductor according to claim 1 , wherein the cationic organic molecule is diethylmethylammonium. 3 . The proton conductor according to claim 1 , wherein the oxoacid anion is trifluoromethanesulfonate. 4 . The proton conductor according to claim 1 , wherein the protic ionic liquid is diethymethylammonium-trifluoromethanesulfonate. 5 . The proton conductor according to claim 1 , wherein the metal ion is an aluminum ion. 6 . The proton conductor according to claim 1 , wherein the coordination polymer has an absorption energy on platinum that has an absolute value less than an absolute value of −1.76 eV. 7 . A fuel cell comprising: a pair of electrodes; and an electrolyte membrane interposed between the pair of electrodes, wherein the pair of electrodes include: a catalyst containing platinum; and an ionomer including the proton conductor according to claim 1 .
