BaUard Power Systems, the leader in the manufacture of PEEC stacks, has sold at least fifty 3- to 5-kW units worldwide. BaUard is involved in a program in Canada to demonstrate a 120-kW PEEC stack to power a transit 20-passenger, 9752-kg bus. Eor this demonstration, on-board compressed hydrogen, sufficient for 150-km range, is the fuel. [Pg.585]

Ballard Power Systems, in conjunction with the province of British Columbia and the government of Canada, have converted a diesel bus for Vancouver, B.C. Transit (43). This 9.1-m vehicle is powered by a 105-kW fuel cell. Gaseous hydrogen, stored on board the bus in DOT-approved glass-wound composite cylinders operating at 20.7 MPa (3000 psi), provides the necessary fuel requited for the 150-km projected vehicle range. [Pg.462]

The Hydrogen Research Institute in Canada has developed and tested a stand-alone renewable energy system composed of a 10 kW wind turbine, a 1 kWpeak photovoltaic array, a 5 kW alkaline electrolyzer, and a 5 kW PEM fuel cell. The components of the system are electrically integrated on a 48 V DC bus [50]. [Pg.178]

The Hydrogen Bus Technology Validation Program in Davis/ Sacramento, California is a multi-district partnership of the City of Davis, Yolo County Transportation District (YCTD), University of California, Davis (UC Davis), UniTrans (Transit authority for the City of Davis and UC Davis), and NRG Tech. [Pg.175]

A commercial CNG bus with a John Deere 8.1 liter engine will undergo modifications to the engine for operation on a mixture of 30% hydrogen and 70% natural gas by volume. This is expected to reduce emissions of NOx substantially without a significant reduction in engine power. [Pg.176]

A fuel cell car, bus or truck is in essence an electric vehicle powered by a stack of hydrogen fueled cells that operates like a refuelable battery. A battery uses chemical energy from its component parts, while a fuel cell uses an electrochemical process to generate electricity and receives its energy from the hydrogen fuel and oxygen that are supplied to it. Like the plates in a battery, the fuel cell uses an anode and cathode, attached to these are wires for the flow of current. These two electrodes are thin and porous. [Pg.266]

A study that was conducted in Canada consisted of a survey of passengers of a test hydrogen bus (Hickson et al., 2007). The results showed a wide-scale preference for hydrogen buses over conventional buses and a strong overall support for hydrogen as a motive fuel. The positive attitude was higher amongst males and more frequent bus users. [Pg.265]

One of the applications for hydrogen is for Polymer Electrolyte Membrane (PEM) fuel cells. As mentioned earlier, one application is a hydrogen fuelled hybrid fuel cell / ultra-capacitor transit bus program where significant energy efficiencies can be demonstrated. Another commercial application is for fuel cell powered forklifts and other such fleet applications that requires mobile electrical power with the additional environmental benefits this system provides. Other commercial applications being developed by Canadian industry is for remote back-up power such as the telecommunications industry and for portable fuel cell systems. [Pg.36]

Recently, the major activity in transportation fuel cell development has focused on the polymer electrolyte fuel cell (PEFC). In 1993, Ballard Power Systems (Burnaby, British Columbia, Canada) demonstrated a 10 m (32 foot) light-duty transit bus with a 120 kW fuel cell system, followed by a 200 kW, 12 meter (40 foot) heavy-duty transit bus in 1995 (26). These buses use no traction batteries. They operate on compressed hydrogen as the on-board fuel. In 1997, Ballard provided 205 kW (275 HP) PEFC units for a small fleet of hydrogen-fueled, full-size transit buses for demonstrations in Chicago, Illinois, and Vancouver, British Columbia.

EPR studies showed that RsSi radicals (R = Me, Et, i-Pr and t-Bu), obtained by hydrogen abstraction from the parent silanes by photogenerated t-BuO radicals, add to Ceo to form the corresponding adducts [29], The spectra of MesSi- and t-Bus Si-adducts have hyperfine structure due to 9 and 27 equivalent protons, respectively, at 27 °C suggesting free rotation of Si—C bonds on the EPR time scale. On the other hand, the middle members of the series, EtsSi-and z-Pr3 Si-adduct radicals, showed a unexpected hyperfine manifold which has been accommodated with free rotation about the Si—Ceo and frozen rotation about the Si—R bonds on the EPR time scale. [Pg.199]

Italy - the first hydrogen-powered urban fuel cell bus was developed by Iveco/lrisbus for the municipal transport authority of Turin in 2001. The bus, in hybrid configuration, is fuelled with hydrogen (electrolysis) and equipped with a battery system. The fuel cell is supplied by International Fuel Cells and has a power rating of 60 kW. [Pg.40]

Canada has a long history of hydrogen and fuel cell demonstrations. In 1993, the world s first fuel cell bus was displayed and in 1996, a second generation bus was demonstrated. With the success of these first fuel cell buses, a bus fleet demonstration was launched in 1997 which integrated numerous HFC technologies and illustrated that fuel cells and ancillary components could function as a whole system. Highlights include ... [Pg.42]
