  1. 21. 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

  3. 22. 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.

    Abstract : Fuel cell systems are becoming more commonplace as a power generation method and are being researched, developed, and explored for commercial use, including portable fuel cells that appear in laptops, phones, and of course, chargers. This thesis examines a model constructed on inspiration from the myFC PowerTrekk, a portable fuel cell charger, using COMSOL Multiphysics, a finite element analysis software. READ MORE

  5. 24. An environmental perspective on the feasibility ofusing existing PEMFC technology in general aviation.

    University essay from KTH/Farkost och flyg

    Author : Victor Karlsson; David Ahlmark; [2013]
    Keywords : ;

    Abstract : The feasibility of using alternative energy solutions in general aviation is investigated; more specifically the usage of Proton Exchange Membrane Fuel Cell (PEMFC) technology, with the help of a constructed reference case. The constructed case is a modified Socata TB20 GT aircraft, equipped with PEMFC technology. READ MORE

  6. 25. Hydrogen as energy backup for the Hexicon : A case study on Malta

    University essay from KTH/Energiteknik

    Author : Filipe Rebello de Andrade; [2013]
    Keywords : Desalination; Electrolysis; Fuel Cell; Hexicon; Hydrogen; Malta; Reverse Osmosis; Wind;

    Abstract : The island of Malta is highly reliant on fossil fuels for its power (99%), and due to climate mitigation policies implemented by EU the Maltese government is required to have 10% of its power generation from renewables by 2020. To achieve these energy goals, the Maltese government has expressed interest in investing on a Hexicon platform to produce 9% of the Maltese energy demand. READ MORE
