Orion TM1 Self-Supporting Membrane


Orion TM1 membrane has been proven by NREL to be the top AEM performer in the world. NREL analyzed over 50 global submissions of AEM for retention of performance at 80°C/1000 hours. Orion TM1 was the only polymer that maintained its conductivity, ion exchange capacity and mechanical integrity over the course of the testing. See NREL ECS 92 (8) Meek et. al., on this website under the NREL study tab. TM1 is PPN5 in the study, the highest performing ionomer analyzed. The second best performance was attained by Orion’s Next Gen material BN2, PPN4 in the study, with Orion holding the top 2 spots for breakthrough AEM performance.
