From page 18...
... Despite all of the challenges associated with fuel cell technology, vehicles powered by fuel cells promise zero tailpipe emissions with improved fuel efficiency and fuel flexibility. Alternative fuel sources in the transportation technology portfolio are preferred, so that no matter what changes occur in the fuel industry, people and goods can move around.

From page 19...
... Well over 90 percent of fuel cell industry funds are not spent on the membrane but on moving these gases in and out of the fuel cell stack, FIGURE 3.1 Configuration of a typical proton exchange membrane (PEM) fuel cell.

... The actual commercial problem, development of a fuel-cell-powered vehicle that has a life of 15 years and 150,000 miles under terrible external environmental conditions, has not been approached. Fuel cell technology may be developed to permit its use for power generation in the near future, but the cost is prohibitive for vehicle transportation.

... However, the addition of a hybrid battery up to the peak of 60 percent of a 60/40 battery/fuel cell stack yields a 50 percent improvement in fuel efficiency. While the battery has no ability to provide independent primary energy, hybridization is still an amazing new technology, especially since speed, start-up launch, and performance improve for the customer.

... Fortunately, there is an institution like the California Fuel Cell Partnership, which is not just localized to California but is the world's fuel cell partnership. It is the only institution in the world that involves major public sector players, the major energy providers, and the major auto companies of the world.
