    • An advanced fuel cell simulator 

      Acharya, Prabha Ramchandra (Texas A&M University, 2005-11-01)
      Fuel cell power generation systems provide a clean alternative to the conventional fossil fuel based systems. Fuel cell systems have a high efficiency and use easily available hydrocarbons like methane. Moreover, since ...
    • Analysis and design of high frequency link power conversion systems for fuel cell power conditioning 

      Song, Yu Jin (Texas A&M University, 2005-11-01)
      In this dissertation, new high frequency link power conversion systems for the fuel cell power conditioning are proposed to improve the performance and optimize the cost, size, and weight of the power conversion systems. ...
    • Analysis and design of power conditioning systems 

      Harfman Todorovic, Maja (2009-05-15)
      A combination of high prices of fossil fuels and the increased awareness of their negative environmental impact has influenced the development of new cleaner energy sources. Among various viable technologies, fuel cells ...
    • Design of a Control Strategy for a Fuel Cell/Battery Hybrid Power Supply 

      Smith, Richard C. (2010-01-14)
      The purpose of this thesis is to design hardware and a control strategy for a fuel cell/battery hybrid power supply. Modern fuel cell/battery hybrid power supplies can have 2 DC/DC converters: one converter for the battery ...
    • Electrospun/Electrosprayed Aligned Fuel Cell Electrodes 

      Kleiderer IV, Arthur Conrad (2017-07-20)
      Proton exchange membrane fuel cells (PEMFCs) are a promising technology in energy conversion. However, the high cost of the platinum catalyst limits the use of fuel cells. To address this problem, many improvements and ...
    • A feasibility study of internal evaporative cooling for proton exchange membrane fuel cells 

      Snyder, Loren E (Texas A&M University, 2006-04-12)
      An investigation was conducted to determine the feasibility of using the technique of ultrasonic nebulization of water into the anode gas stream for evaporative cooling of a Proton Exchange Membrane (PEM) fuel cell. The ...
    • Fuel Cell Development with Non-Precious Metal Catalysts 

      Ayyildiz, Burak Celal (2016-06-28)
      Proton exchange membrane (PEM) fuel cells are clean energy sources which are offering solutions to some problems that are caused by climate change and global warming. One of the biggest obstacles in the way of development ...
    • Increasing the CO tolerance of PEM fuel cells via current pulsing and self-oxidation 

      Thomason, Arthur Hugh (Texas A&M University, 2004-09-30)
      An investigation was conducted to determine and compare the effect of cell current pulsing and "self-oxidation" in increasing the CO tolerance of a PEM fuel cell. The most effective pulsing parameter values were also ...
    • Multiport Converter Topologies for Distributed Energy System Applications 

      Hawke, Joshua (2014-07-28)
      In the midst of a present-day global energy renaissance, power electronics has evolved into a top-tier technology discriminator in distributed energy resource (DER) systems. Faced with the formidable task of integrating ...
