摘 要：Prepared by the Federal Transit Administration (FTA) Office of Research, Demonstration, and Innovation (TRI), this report summarizes the accomplishments of fuel-cell-transit-bus-related research and demonstrations projects supported by FTA through 2011. It catalogs fuel cell electric bus research projects in the United States and describes their impact on commercialization of fuel cell power systems and electric propulsion for transit buses. Few barriers remain to reaching full commercialization of fuel cell electric buses. This report documents progress toward overcoming these barriers.
