1. 11. 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.

3. 12. Electrifying Agricultural Implements : A study of design implications of electrification

   University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

   Author : Jonatan Magnusson; Pettersson Eric; [2023]
   Keywords : Electrification; Agriculture; Electrified implements; 48 V; Agricultural electrification; Electromechanics; Mechatronics; Mechanical Engineering; Product development; Case study;

   Abstract : As the world seeks to become less reliant on fossil fuels and use more electric energy instead new possibilities for development of agricultural implements opens. Major tractor manufacturers have recently announced tractors with over tenfold increases in electrical power. READ MORE

4. 13. Power system balancing in Swedish future scenarios of 2045 - Estimating contributions from V2G

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Pontus Herrmann; Julia Jonasson; [2023]
   Keywords : Technology and Engineering;

   Abstract : The ongoing climate change calls for an immediate decarbonization of society, where one important measure is a rapid transition of the energy system through an expansion of variable renewable energy sources, such as wind and solar photovoltaic power production. This transition imposes new challenges to the electrical power system, not least from a power balance perspective. READ MORE

5. 14. Alternative traction system for road-rail vehicles

   University essay from Lunds universitet/Innovation

   Author : Jakob Runevad; [2023]
   Keywords : Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

   Abstract : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. READ MORE

6. 15. Designing a Cost Effective Encoder for High Performance Doors

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Emanuel Edelstam; David Petersson; [2023]
   Keywords : Encoder; High speed doors; Motor; Product development; Prototyping; ASSA ABLOY; Technology and Engineering;

   Abstract : Målet med detta arbete var att utveckla en prototyp av en kostnadseffektiv pulsgivare till motorerna för ASSA ABLOYs snabbrullduksportar. Pulsgivaren ger återkoppling till de automatiska dörrarnas kontrollsystem och ska göra detta på ett tillförlitligt sätt samtidigt som de ska vara mer kostnadseffektiva än de nuvarande lösningarna som används på ASSA ABLOY.
