The synthesis of alkyl, nitro and halogeno derivatives of benzo-15-crown-5, benzo- 18-crown-6 and naphtho-15-crown-5 has been reported. Also some novel ester type bis(crown ether)s have been prepared. Some of the compounds have been characterized as electroactive substances in PVC membrane Ion-selective electrodes.
A membrane electrode assembly for fuel cells includes a proton conducting membrane having a first side and a second side. The proton conducting membrane in turn includes a first polymer including cyclic polyether groups and a second polymer having sulfonic acid groups. The membrane electrode assembly further includes an anode disposed over the first side of the proton conducting layer and a cathode catalyst layer disposed over the second side of the proton conducting layer.
