Products – High-Temperature MEAs

High Temperature MEAs

Advent’s original high temperature membrane is based on pyridine type structures incorporated around a stable polymer backbone. MEAs with this polymer are called Advent TPS® MEAs and are known to operate 120 °C to 200 °C – the highest for this class of MEA. Advent also fabricates a polybenzimidazole (PBI) based MEA under a license from BASF. Advent’s PBI MEA uses the same materials and assembly processes as developed by BASF for the P1100W HT-MEA and are known for having the highest phosphoric acid content of any of the high temperature membranes. Both materials use phosphoric acid as the electrolyte, do not need water for conductivity, and are based on polymers with excellent thermal and oxidative stability.
