On-board fuel reforming for fuel cells is an important strategic option in the development of mass production fuel cell vehicles. The concept prototype Jeep Commander 2 implements a methanol reforming fuel cell engine with a 90 kW NiMH battery pack. The Jeep Commander 2 was able to overcome many challenges with on-board fuel reforming for PEM fuel cell by hybridization, use of lightweight body construction and more available packaging space. Although the fuel cell stacks have improved in weight and volume, the fuel processing system must make the same improvements. These reductions are necessary for fuel reforming fuel cell engines to achieve acceptable start-up time and competitive performance against ICE vehicles. The Jeep Commander 2 hybridized electric powertrain overcomes the limitations of the current fuel reforming system. Preliminary road and dynamometer testing of the Jeep Commander 2 show good driving performance, fuel economy and emissions results. The high voltage battery provides instant power-on-demand to satisfy the driver's performance needs and a liquid fuel reforming fuel cell engine to provide the fuel economy, emissions and driving range acceptable to most customers. However, more technological innovations are needed for the reforming fuel cell engines to achieve competitive levels of power density, cost and reliability, as compared to internal combustion engines. In October 2000, DaimlerChrysler introduced the Jeep Commander 2 methanol fuel cell hybrid electric vehicle at the Environmental Conservation Conference in Lansing, Michigan.
