The MEA (Membrane-Electrode-Assembly) determines weight, power, lifetime, total cost of ownership of the fuel cell, and infrastructure investment. 

MEA: The “heart” of the Fuel Cell

Advent continuously advances the field of MEAs having set the following goals:

Advent’s high-temperature membrane

 is based on pyridine type structures incorporated around a stable polymer backbone. Advent TPS® MEAs operate at 120 °C to 200 °C. 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 has 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.

Advent has recently expanded its production capacity in Massachusetts, USA and Patras, Greece and can provide highly competitive prices for the best MEA in the market.
