Test cells using the above graphite materials were evaluated in PC-based electrolytes. For this work, the hybrid pulse power characterization (HPPC) test was performed on cells with the different graphite anodes and PC-based electrolytes to evaluate their high power capabilities. These electrochemical experiments indicate that cells containing the surface-modified natural graphite can meet the power requirement set by the FreedomCar partnership for the hybrid vehicle applications.

The two fuel vehicles began operation late in the summer of 2007. Users maintain logs that document vehicle performance, and tests are ongoing to evaluate the operational experience and the refueling station. Other NREL evaluation projects involve transit buses powered by fuel cell hybrids in Oakland, California, Thousand Palms, California, and Hartford, Connecticut. 

While these hybrid vehicles are operating at voltages of 100-300 V, Ni-MH batteries may also be considered for 42-V PowerNets due to their excellent cycling performance, which is currently more than ten times better than that of the most advanced lead-acid systems. To avoid packaging problems and to facilitate integration into the vehicle, Ni-MH battery prototypes for the 42-V PowerNet have been produced with the standard outer dimensions [39]. 

At the vehicle systems level, there are thousands of interacting parameters that can influence the performance of a fuel cell vehicle. ADVISOR makes the task of quantifying the impacts of these parameters easier. However, studies that go beyond one or two parameters are difficult to do through manual iteration. Optimization tools have been incorporated into ADVISOR by NREL to automate the process of multi-dimensional analysis of fuel cell hybrid vehicles. 

In Phases 1 and 2, TIAX developed detailed well-to-wheel performance and cost calculations, taking into account technology options, system integration and efficiencies, hybridization, vehicle weight, and drive cycle. Last year s annual report included some of the results from these Phases in this report, we present those results which were not previously reported. 

So long as petroleum is still widely available, it is difficult to forecast which of the various HEV options will prove to be most successful over the next decade or two. Indeed, fuel-cell enthusiasts consider both diesel and hybrid vehicles to be merely an interim technology until the day when FCVs are mass produced. Others are more sceptical over the future for FCVs and favour hybrids. Yet others see the hybrid as an expensive option with a performance that does not fully match that of a petrol engine. At present, it is impossible to say which view is correct the market will decide in the light of factors such as the extent to which hybrid technology progresses, the resulting vehicle prices, the future availability and cost of petroleum, and the possible imposition of carbon taxes or emission permits. 

The default assumptions for each vehicle type are summarized in Table 8.1. The assumed cost and performance of the gasoline hybrid and electric vehicles are based on current technology. The hybrid price and estimated mileage is based on the average retail price and efficiencies of the three existing hybrid vehicles on the market - the Honda Insight, the Honda Civic, and the Toyota Prius. The cost and performance of the electric vehicle (EV) is based on the recently retired GM EVl. 

Toyota designed and produced the industry s first high-performance hybrid vehicle in 2004. The vehicle, which seats three people and has a carbon-fiber body, was...
