Advent Technologies to collaborate with Los Alamos in the development of next-generation HT-PEM fuel

The program is funded by an Advanced Research Projects Agency–Energy (ARPA-E) OPEN award.

We at Advent are committed to bringing HT-PEM technology to the market. Drawing on our leadership team’s decades of experience, we intend to commercialize and scale-up membrane electrode assembly (MEA) production while working closely with Tier-1 manufacturers and original equipment manufacturers. We believe that HT-PEM represents not only a breakthrough for heavy-duty automotive technology but also for aviation, portable, and off-grid power generation.

Dr. Emory DeCastro, Advent’s Chief Technology Officer, added that these developments have the potential to drop overall fuel cell system costs by 25% and enable higher power density and simplify packaging constraints.

Furthermore, the potential to use eFuels instead of hydrogen can provide a significantly lower total cost of ownership and allow for faster deployment of fuel cell technology across the industry.

The purpose of the development program is to use HT-PEM technology operating at 80 ˚C - 150 ˚C to achieve a variety of objectives, including:

1. High Energy Efficiency: The target efficiency of the HT-PEM simplified fuel cell system is 70% vs. 60% for current incumbent technology; thereby providing a significant total cost of ownership advantage. This is especially important for long haul trucks using hydrogen fuel cells.

2. Fast Startup Time: Develop extremely stable fuel-cells that can start under nearly water-saturated conditions.

3. Superior Heat Management: Completely remove the external humidifiers/demisters and substantially reduce the size of the radiator. Various industry sources have stated that radiators for Class 8 Trucks running with low-temperature polymer electrolyte membrane (LT-PEM) technology are an enormous challenge. There is evidence that the size of the radiator required to run a Class 8 truck in hot and dry conditions (i.e. in places such as Nevada, Australia, Africa and India) is impractical and will pose a huge challenge for the deployment of current fuel cell technology. Next-generation HT-PEM technology aims to solve this problem.

4. Increase Lifetime: Boost tolerance to impurities and improve performance with platinum and non-platinum catalysts.

5. Address the hydrogen infrastructure challenge: Allow for the direct reformation of a variety of fuels (natural gas, methanol, ethanol, and zero-carbon emissions eFuels of the future) to low grade (impure) hydrogen within the vehicle, thus bypassing the need for expensive hydrogen storage, transportation, and de/compression technology and hydrogen refill stations.
