Actually that's not the site I got it from.
It came from a Japanese site about electric vehicles, where it was described as being part of a state programme for developing electric cars and was described as "Battery/Fuel Cell Design Package 12", so I'll call it solved as you have got just about all of it.
Oddly the site never mentioned Honda at all, but I took it that it was not a standard Honda EV as I don't think that would be described as a Fuel Cell vehicle. I may be wrong though, as the words were translated from Japanese using Google Translate, and maybe it's just a standard car. I'll try to find the site again and see if I can glean any further information.
