In a press event at its R&D facility north of Tokyo, Honda showcased its FCX Concept fuel cell vehicle (earlier post), putting it through its paces on the test track at about 100 mph. The company says it plans limited marketing in Japan and the US for the vehicle starting in 2008.
In January of this year, Honda had indicated it would begin production of its next-generation FCX hydrogen fuel cell vehicle (FCV) in three to four years. The 2008 date indicates ongoing rapid advancement in Honda’s technology.

The FCX Concept uses a new, compact 3V System fuel cell platform that enables the lowest-floor platform in a fuel cell vehicle yet. Oxygen and hydrogen flow from the top to the bottom of the fuel cell stack (Vertical gas flow) and the fuel cells are arranged vertically in the center tunnel (Vertebral layout) for new, high-efficiency fuel cell packaging (Volume efficiency).
The new stack delivers 100 kW of power, compared to the 86 kW of the 2006 FCX. The key to the fuel cell’s performance is water management; Honda’s new system takes full advantage of gravity to efficiently discharge water formed during electricity generation.
Honda also used the event to re-emphasize its planned introduced of a Tier 2 Bin 5 compliant diesel in the US by 2009.
In deliver the required emissions performance, Honda is concentrating on advanced combustion management with Premixed Charge Compression Ignition (PCCI) and a trap-type lean NOx catalyst (LNC). (Earlier post.)
