2. 1. Durability evaluation of PEM fuel cell components

   Author : Live Mølmen; Peter Leisner; Lars Fast; Frode Seland; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Proton exchange membrane fuel cell; bipolar plate; corrosion; interfacial contact resistance; electrocatalysis; Polymermembranbränsleceller; bipolära plattor; korrosion; kontaktresistans; katalys;

   Abstract : Proton exchange membrane fuel cells (PEMFCs) are used to convert hydrogen and oxygen to electricity, heat, and water. There are no greenhouse gas emissions, given that the hydrogen is produced from renewable sources, such as water electrolysis from wind, hydro or solar energy. READ MORE

4. 2. Materials Reliability in PEM Fuel Cells

   Author : Live Mølmen; Peter Leisner; Ulf Jansson; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; PEMFC; Bipolar plate; Catalyst; Electrodeposition; Corrosion; Stainless steel; Accelerated stress tests; bränsleceller; PEM; bipolära plattor; katalysator; elektroplätering; korrosion; accelererad testning;

   Abstract : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. READ MORE

5. 3. Thin-Film Coated Steel Foils as Interconnects for Solid Oxide Fuel Cells (SOFC)

   Author : Rakshith Nugehalli Sachitanand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interconnect; Fuel Cell; Energy; SOFC; Steel; Corrosion;

   Abstract : Solid Oxide Fuel Cells (SOFCs) are electrochemical energy conversion devices that have the potential to achieve high efficiencies while using a broad range of fuels. The advancement of the technology has however been hindered by a number of technical and economic barriers, one of which is the durability and cost of the bipolar plate or interconnect that connects individual cells in series to form a so-called ‘stack’.
