increased the hydrogen gas pressure to 350 bar. the dispenser then
transferred the hydrogen gas to the
vehicles according to the society of
automotive engineers J2601 standard. the fleet of vehicles refueling
during the trial period included a
set of Fc vehicles with power ranging from 3 kw to 100 kw.
