  1. 1. Surface Engineering of Bipolar Plates for PEM-Water Electrolysis : Cost-Effective Corrosion Protection

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Tristan Dettke; [2021]
    Keywords : Hydrogen; Water Electrolysis; Fuel Cells; Bipolar Plates; Thin Films; Coatings; Impact Coatings; IFM; Tristan Dettke; PEM;

    Abstract : Hydrogen production by PEM-Water electrolysis is an environmentally benign and promising approach to store excess energy from renewable energy sources but facing drawbacks of high costs, mainly due to a harsh cell-environment. The aim of my Master Thesis was to reduce the costs of the most expensive cell component, the bipolar plate by surface engineering. READ MORE

  3. 2. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE

  4. 3. Corrosion studies on multicomponent TiZrNbTa thin films

    University essay from Uppsala universitet/Strukturkemi

    Author : Asker Jarlöv; [2020]
    Keywords : Corrosion resistance; Multicomponent thin-film; High entropy alloy; TiZrNbTa; Bipolar plates; Magnetron sputtering;

    Abstract : The goal of this work was to evaluate the electrochemical properties of TiZrNbTa thin films deposited by magnetron sputtering using an industrial physical vapor deposition system. Samples were deposited on both Si(001) and 316L stainless steel. READ MORE

  5. 4. Accelerated degradation of bipolar plates in the PEMFC

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Marcus Eriksson; [2016]
    Keywords : ;

    Abstract : The aging of bipolar plates in the polymer electrolyte membrane fuel cell was evaluated using different accelerated degradation tests. From previous studies, it is well known that the startups and shutdowns of a polymer electrolyte membrane fuel cell is the primary cause of fuel cell component degradation. READ MORE
