One of the most pressing technical challenges in fuel-cell research and development for HDVs is the greater demand for durability, with 4 to 5x improvements in lifetime to achieve the M2FCT goal of 1 million mile (1.6 million km). Overcoming this challenge requires not only the design and interrogation of robust materials for more durable cells, but also the durability protocol development and lifetime prediction models to guide the material and cell design. An essential ingredient of durability efforts for fuel-cells is the Accelerated Stress Testing (AST) for Heavy-Duty Fuel Cells, which is one of the focus areas and milestones in the M2FCT consortium.
To realize this goal more effectively and to accelerate the research output, M2FCT has formed an AST working group (ASTWG) with the following objectives and partners.
Define the 25,000-hour equivalent AST in the M2FCT 2025 Target
- Recommend protocols and targets related to heavy-duty application of fuel cells
- ASTs for use in M2FCT for target evaluations (targets are End-of-Life)
- Accelerated Stress Tests (ASTs) to be developed
DOE & National Labs: LANL, LBNL, NREL, ANL, ORNL
Industry & Academia: 3M, Ballard, Carnegie Mellon, Chemours, Cummins, GM, Nikola, Plug Power, W.L. Gore
ASTWG meets every other month to discuss the current protocols and progress, seek input and feedback from Industry stakeholders and researchers in labs and academia.
We are also currently establishing an International group with representation from the US, EU, Japan and Korea.
M2FCT is also leading efforts to establish an international group of researchers interested in the development of fuel cells for HDV applications. M2FCT has teamed up with researchers from the EUs IMMORTAL (IMproved lifetiMe stacks fOR heavy-duty Trucks through ultra-durabLe components) project funded by FCH 2 JU and researchers from Japan’s FC-Platform project funded by NEDO to promote international collaborations.
The M2FCT consortium had a very productive meeting with members of the IMMORTAL Consortium where researchers from both M2FCT and IMMORTAL presented their work scope and identified areas of cooperation and collaboration. The first international meeting (online) of researchers from the US. ASTWG, M2FCT, IMMORTAL, FC-Platform, and International OEMs were held on the 27th of May with over 40 participants representing Governments, Universities, labs, and companies from Asia, the EU, and the USA. It was decided that this group will meet every two months and will initially focus on facilitating data sharing to promote AST development for fuel cells in heavy-duty applications.
