Honda has expanded hydrogen storage capacity with a hydrogen absorption material in the FCX tank, which doubles capacity to 5 kg of hydrogen at 5000 PSI. The capacity increase extends cruising range to 350 miles. The range is equivalent to that of a gasoline-engine car. ...
... "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). Compact enough to fit neatly into the center tunnel but robust enough to put out 100kW of power, Honda's V Flow fuel cell stack offers space efficiency and high-energy output. The key to fuel cell performance is water management; Honda's new system takes full advantage of gravity to efficiently discharge water formed during electricity generation. This improves performance in sub-zero temperatures, further solving the problem of cold-weather startup that has been a key obstacle to the commercialization of FCV's. " ...
