  1. 1. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  6. 5. Extreme precipitation events in the Sichuan Basin and their connection to mesoscale disturbances

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Anna Dugoul; [2022-10-04]
    Keywords : ;

    Abstract : The Sichuan Basin (SB) is a region with frequent extreme precipitation during summer, principally as a result of its location and topography, with the most extreme events possibly leading to floodings and landslides. A better understanding of these extreme events’ characteristics and triggers could help to improve forecasting methods, while improving the knowledge about climate dynamics in the region is crucial for climate change studies.
