Bipolar Plates for PEM Systems
Lædre, Sigrid (Doctoral thesis at NTNU;2016:247, Doctoral thesis, 2016)Summary of thesis: The Bipolar Plate (BPP) is an important component in both Proton Exchange Membrane Fuel Cells (PEMFCs) and Proton Exchange Membrane Water Electrolyzers (PEMWEs). Bipolar plate material and processing ... -
Electroplating of Stainless Steel in Aqueous Alkaline Solution
Thu, Ida Soland (Master thesis, 2017)Electroplated stainless steel alloys containing elements such as iron, chromium and nickel, are of great interest in production of electronics and nanotechnology devices. Previous methods for electroplating of these alloys ... -
Investigation of metallic bipolar plates for PEM fuel cells
Lædre, Sigrid (Master thesis, 2011)High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ... -
Materials for Proton Exchange Membrane water electrolyzer bipolar plates
Lædre, Sigrid; Kongstein, Ole Edvard; Ødegård, Anders; Karoliussen, Håvard; Seland, Frode (Journal article; Peer reviewed, 2017)Titanium based BiPolar Plates (BPPs) are commonly used in Proton Exchange Membrane Water Electrolyzers (PEMWEs) today as they can withstand the harsh operating conditions experienced inside an operating PEM water electrolyzer. ... -
Measuring In Situ Interfacial Contact Resistance in a Proton Exchange Membrane Fuel Cell
Lædre, Sigrid; Kongstein, Ole Edvard; Ødegård, Anders; Seland, Frode; Karoliussen, Håvard (Journal article; Peer reviewed, 2019)Interfacial contact resistance (ICR) is one of the remaining hurdles for successful implementation of stainless steel bipolar plates in PEM fuel cells. We have developed a reliable method, using thin gold wires, to measure ... -
Multilayer Coated Aluminium Bipolar Plates for Light-weight Fuel Cells
Mustaparta, Maria Amundsen (Master thesis, 2022)Den moderne verdens største utfordring er å holde seg innenfor grensene for akseptabel global oppvarming. Klimagassutslipp må derfor reduseres. Flytrafikk er en enorm bidragsyter til klimagassutslipp verden over. ... -
Ta-ITO Coated Titanium Bipolar Plates for Proton Exchange Membrane Water Electrolyzers
Lædre, Sigrid; Mendizabal, Lucia; Kongstein, Ole Edvard; Ødegård, Anders; Karoliussen, Håvard; Seland, Frode (Peer reviewed; Journal article, 2022)A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top layer was applied to titanium substrates. Samples were polarized ex situ in a parameter study, where the pH, potential and ... -
Tin and Tin Alloys for Low Cost Bipolar Plates in PEM Fuel Cells
McCay, Katie (Doctoral theses at NTNU;2020:408, Doctoral thesis, 2020)Proton Exchange Membrane (PEM) Fuel Cells are one of the most promising futures for green energy, as they provide a sustainable alternative to combustion engines in vehicles. The bipolar plate (BPP) is a crucial component ...
