Prevention of austenitic stainless steel from hydrogen embrittlement in hydrogen fuel cell by surface engineering

Research Project, 2021 – 2022

Purpose and goal: Hydrogen fuel cell is a promising power sources as it is clean, efficient and sustainable. Many metallic components exposed to hydrogen in such system are made from austenitic stainless steels.
The current proposal looks for surface treatments, low temperature carburizing, to protect the material from embrittlement. The mechanical properties, stability and reliability during service of so-called expanded austenite with pre-charged hydrogen will be addressed. Another task is to develop a large consortium including more industry sectors and to plan a full-scale project. Expected results and effects: A successful implementation of the project will contribute to improved competitiveness for the Swedish metal and engineering industry, making them be able to take a leading position towards the utilization of hydrogen energy. The results from the project will open-up new commercial alternatives for the industry who utilize hydrogen energy. When completed, the results will be disseminated in program conferences, international conferences and publications. The project will benefit further development of partnerships and a full-scale project proposal for the next phase.
