High Temperature PEM Products


Advent Technologies is the foremost company in the development of High Temperature Membrane Electrode Assemblies (HT-MEAs) for use in high temperature proton exchange membrane (HT-PEM) fuel cells. Founded in 2005 to capitalize on a new class of HT membranes, Advent is dedicated to the development and production of innovative materials that support our customer’s commercialization of applications derived from these advanced materials.

HT-PEM Technology enables simple and cost effective fuel cell systems that can operate on fuel sources available today, such as natural gas, propane, and methanol. When compared to low temperature PEM fuel cells, subsystems for membrane humidification and carbon monoxide clean up from reformate can be eliminated.

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.

Advent introduces two new HT PEM stack designs for intermediate temperature fuel cells (ITFC). Our IANUS series represents years of development and is available in one and three kilowatt configurations. The IANUS stack is liquid cooled and introduces a key innovation of direct generation of steam. When the steam is used for reforming, one obtains excellent thermal integration and efficiency. The steam can also be used for heating or cooling. Thus, an IANUS stack is the core power supplier for combined heat and power systems.

The ARGO series is an air cooled stack that can be configured in a power range from 100W to 500W. This platform is designed for those whose applications benefit from reformed high energy fuels such as battery range extenders and remote power for surveillance. The ARGO series is also appropriate for those wanting to evaluate HT PEM at a research and design level.
