  1. 6. Model on degradation of PEM fuel cells in marine applications

    University essay from KTH/Kemiteknik

    Author : Erik Östling; [2021]
    Keywords : Proton exchange membrane fuel cell PEMFC ; marine applications; durability; lifetime prediction; empirical model; PEM bränsleceller; marina tillämpningar; hållbarhet; livslängdsberäkning; empirisk modell;

    Abstract : Sjöfarten står för 3 % av världens totala växthusgaser och är idag högst beroende av fossila bränslen. Ett alternativ för att gå över till en fossilfri flotta är användning av bränsleceller och vätgas som drivmedel. READ MORE

  3. 7. Hydrogen - The future fuel for construction equipment? : A well to tank analysis of hydrogen powered machine applications at Volvo CE

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Andreas Sjödin; Elias Ekberg; [2020]
    Keywords : Hydrogen; Well to tank; Hydrogen storage; MILP;

    Abstract : As the world is moving towards a more sustainable energy perspective, construction equipment sees the requirement to change its current way of operation with fossil fuels to reduce its environmental impact. In order to pursue the electrification of construction equipment a dense power source is essential, where hydrogen powered fuel cells have the potential to be a sufficient energy source. READ MORE

  4. 8. Poly(p-terphenyl piperidinium) as anion exchange membranes. Synthesis and evaluation of properties

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hugo Selling; [2020]
    Keywords : Fuel cells; Alkaline exchange membrane fuel cells; Anion exchange membrane fuel cells; Polymer technology; Polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Alkaline exchange membrane fuel cells (AEMFC) is an interesting and attractive alternative to proton exchange membrane fuel cells (PEMFC) due to the potential use of non-precious catalysts which can reduce the overall cost of the fuel cell. An important component of the AEMFC is the anion conducting membrane. READ MORE

  5. 9. Fuel Cell for Food Preservation

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Maximilian Spencer; [2016]
    Keywords : food preservation; fuel cell oxygen depletion; proton exchange membrane fuel cells; oxidative food spoilage; Hydrogen fuel cells;

    Abstract : As foodstuffs are being produced, transported and stored in greater quantities than ever before in human history and with an alarming amount of food products being lost to spoilage every year, new, environmentally friendly ways of preserving food products are being actively researched and developed in today’s world. Oxygen is a key pathway towards food decay and destruction, due to its dual roles as a source of respiration for the multitude of microorganisms that can cause food spoilage and through direct destruction through oxidation reactions within food products that cause oxidative deterioration.
