  1. Canada-Israel Technology Innovation Summit 2011 06 July 2011 TelAviv • Fuel Cell Research Group : • Dr. E. Bubis - Electronics • Prof. E. Kroll - Mechanics • Dr. H. Faiger - Chemistry • Prof. P. Schechner – Physical Chemistry Room Temperature Universal Fuel Cell Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  2. The Goal To develop a fuel cell Membrane Electrode Assembly (MEA), able to obtain electricity from any fuel containing the following chemical bonds: At near STP C–H C–C C–O Almost all the fuels • Obtainable from Bio-Mass • wastes (forestry, agricultural, • food processing, etc.) Biodiesel Gasoline • low production costs • easy to transport • easy to store • abundant (50% of the Flora) • Renewable Saccharides Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  3. Three technical limitations of the proposed fuels: Low Power Density and Low Efficiency Slow reaction Strong Chemical Bonds 2 “Polymerization” Big fuel molecules Crossover losses 3 1 We know how to overcome these limitations! Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  4. 1 - Strong Chemical Bonds and “Polymerization” Fuel independent, Anodic Universal Catalyst Alan S. Goldman, Nature, 2010,Organometallic chemistry: Carbon–carbon bonds get a break Tungsten A. Sattler and G. Parkin, Nature, 2010, Cracking carbon-carbon bonds L. Gómez-Hortigüela, F. Corà and C.R.A. Catlow, ACS Catalysis, pp. 18-28, Nov. 2010, Aerobic Oxidation of Hydrocarbons Catalyzed by Mn-Doped … Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  5. What have we done? MEA in a Single Cell Power Density Polarization O- H Fuel: Glucose C C O O Silver anode: Basic matrix for catalytic metal doping Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  6. 2 - Fuel molecules are big Electronic Power Management EPM,(2 examples) 2.1 - Power Multiplexing 2 FCs Multiplexed 1000 W 100 W ~40mA 25% 4 FCs Multiplexed 2 FCs in Parallel Time (min) 100 W Time (s) Time (min) Patent Pending Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  7. 2.2 – UltraCapacitor System 4FC + UC3 Kfarad Increase of the Power Density without heating 4 FC in Parallel For some cases, we can bypass the slowness limitation *Calculated from the Total Anodic Area 73 cm2 Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  8. What has to be done? Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner

  9. Summary 1 – We are developing an Universal STP Fuel Cell MEA for Renewable Fuels. 2 – We have developed a Glucose fuelled FC with PPD> 0.4 W/m2at near STP 3 – Electronic Power Management solves kinetic limitations without investing energy. Our Multiplexing innovation rises the PPD : Multiplexing  PPD +25% (flat as a battery) Multiplexing + UltraCapacitor  Equivalent PPD >> 140 W/m2 Canada-Israel Technology 2011 Universal FC Bubis, Kroll, Faiger & Schechner
