  • Abstract:
    This report presents results of the American Fuel Cell Bus (AFCB) Project, a demonstration of fuel cell electric buses (FCEB) operating in the Coachella Valley area of California. The AFCB, built on an ElDorado National-California 40-foot Axess bus platform, has a fuel-cell-dominant hybrid electric propulsion system in a series configuration. BAE Systems’ hybrid electric propulsion system is powered with a 150-kW Ballard fuel cell system. The prototype AFCB, which was developed as part of the Federal Transit Administration’s (FTA) National Fuel Cell Bus Program, was delivered to SunLine in November 2011 and was put in revenue service in mid-December 2011. Two new AFCBs with an upgraded design were delivered in June/July of 2014 and a third new AFCB was delivered in February 2015. FTA and the AFCB project team are collaborating with the U.S. Department of Energy (DOE) and DOE’s National Renewable Energy Laboratory (NREL) to evaluate the buses in revenue service. NREL evaluates FCEBs under funding from FTA and DOE and uses a standard data-collection and analysis protocol originally developed for DOE heavy-duty vehicle evaluations. The goal of this evaluation is to compare the FCEB performance to that of conventional technology and to track progress over time toward meeting the technical targets set by DOE and FTA. NREL collects data on five compressed natural gas (CNG) buses as a baseline comparison at SunLine. This report covers the performance of the AFCBs from July 2015 through December 2016. Table ES-1 provides a summary of results for several categories of data presented in this report. Data are included on the four AFCBs and on the five CNG baseline buses. The table provides the data analysis for the entire demonstration as well as for the evaluation period that is the focus of the report. From the start of the demonstration through December 2016, the AFCBs have traveled more than 330,500 miles and accumulated more than 23,600 hours on the fuel cell systems.
