Our valued international partner Polytechnique Montréal (Canada) in collaboration with the University of Malaga (Spain) organized a three-day hybrid workshop titled “Hydrogen (H₂) and fuel cells” on the premises of Polytechnique Montréal in Montreal between July 23 and 25, 2025. The workshop attracted more than 110 participants, both in person and online, from industry representatives, professors, students, and startups, with around 40 speakers speaking over the course of the event. This workshop was a valuable opportunity to expand the H2Excellence network overseas and raise its visibility in Canada and North America. A book of abstracts resulting from the workshop has been published and is available at https://riuma.uma.es/xmlui/handle/10630/39511. It can also be accessed via our website at book-of-abstracts-H2-Montreal-2025.pdf.
