Within this framework, a life cycle sustainability assessment (LCSA) of a PEMFC stack was conducted to evaluate its potential environmental, economic, and social impacts. The climate change indicator for one 48 kW$_{el}$ PEMFC stack is 1160 kg CO$_2$ eq., with platinum accounting for 63.5% of the total value. The cost depends mainly on the production rate, and it is 2233 €/stack for an annual production of 50,000 stacks. Social hotspots are mainly associated with platinum production in South Africa. Illustrative ecodesign actions allow a reduction in climate change of 31% and 46% in the realistic (short-term) and optimistic (long-term) concept, respectively. A further reduction in climate change (54% in the optimistic concept) is achieved if 95% recycled Pt is used.20232023-12-07 14:12:37Članek v reviji152816UDK: 502.1ISSN pri članku: 1879-3487DOI: 10.1016/j.ijhydene.2023.05.255COBISS_ID: 156527875sl
