Fuel cells for stationary applications

  • This fuel cell technology is a thin composite membrane of c-axis aligned hydroxyapatite single crystals to optimize proton transport grown on a palladium alloy membrane base. Applications: This membrane is intended to enable a new class of fuel cells to operate in the temperature range of 200-600oC. It may also be useful in gas sensors and electro-catalytic devices.

  • Solid oxide fuel cells (SOFC\'s) are a rapidly maturing form of alternative (clean) energy that is seeing greater media and investment coverage in recent years see Bloom Energy as a leading example. However one challenge in building cost effective SOFC\'s is the high cost of integrating each cell into a stack and effectively routing the necessary air and fuel to each anode and cathode at each cell within the stack.

  • Background: Solid Oxide Fuel Cells operate at high temperatures (750-1000C) introduce difficult challenges related to high materials cost seals and interconnects startup time and long-term durability. Technology Description: This invention describes Sr0.8La0.2TiO3 (SLT)-supported SOFCs with a thin (La0.9Sr0.1)0.98Ga0.8Mg0.2O3-δ (LSGM) electrolyte and porous LSGM anode functional layer (AFL) for low temperature (450C-650C) application.

  • The Nanox SOFC is a room temperature fuel cell in which nano-structured oxides such as YSZ (yttria stabilized zirconia) or SDC (samaria doped ceria) are used as electrolytes. Due to the configuration as concentration cell only water is used and produced during operation of the fuel cell. Commercial Opportunities Conventional solid oxide fuel cells (SOFCs) need operation temperatures above 800 °C. In contrast the Nanox SOFC works at room temperature.

  • Abstract of US Patent 7090891 - Method for fabricating nanostructured solid oxide fuel cells and cell components: A method of fabricating a nanostructured solid oxide fuel cell includes dispersing ceria and doped ceria nanoparticles in a first colloidal solution atomizing the first colloidal solution into a spray depositing the spray onto a substrate to form a thin film electrolyte dispersing a nanocomposite powder including ceria and CuO in the first solution forming a second colloidal solution atomizing the second colloidal solution into a second spray and depositing the second spray over

  • Objective

    The University of Florida is seeking companies interested in commercializing fuel-cell technology with improved range of use. Fuel cells combine oxygen and fuel to chemically generate electricity without combustion. The domestic market for this innovative energy source could grow to $975 million by the year 2012 according to some studies. Of the many existing fuel-cell technologies solid-oxide fuel cells have the distinct advantage of being able to use fuels other than hydrogen allowing for greater flexibility.

  • Objective

    Background: Currently there is a surge in interest in fuel cell research as companies across the globe race to take advantage of the high energy capacity that fuel cells provide in comparison to other portable electrochemical systems. Many approaches to fuel cell technology use strong acid electrolytes. Such systems suffer from corrosion problems which limit their functional life. Despite significant research in the area there remains a need for higher-performance proton carriers for use in fuel cells.

  • Objective

    The technology is a hybrid process that utilizes both sulfur-tolerant and high power density planar solid fuel cell (PSOFC) stacks to produce power at a higher efficiency. The sulfurtolerant PSOFC stack uses anode materials that selectively convert Hydrogen Sulphide (H2S) present in fuel streams to non-poisoning sulfur compounds. The remaining gas balances which are nearly free of H2S are used as fuel inlet to the conventional PSOFC stack.

  • Objective

    This patented electrolyte fabrication method is designed for deposition of low-cost ultra-thin metal oxide film on a porous substrate. The simple clean process prevents gas crossover and generates a low-resistance electrolyte that can operate temperature below 500oC. This electrolyte could be used to create a high efficiency solid oxide fuel cell. Applications: Solid oxide fuel cells - fabrication of ultra-thin film electrolyte.
