Probably a stockmarket scam (Score 1)

A WHOIS lookup shows that genepax.co.jp is all of five weeks old. A bit recent for a company claiming 25 years of research in this area, wouldn't you think? The 300W output of their cell is maybe 2% of the kind of power you'd need to run even a small car as in that video at 80 km/h. In other words, they showed an electric car running on off fully charged batteries (i.e. stored mains grid power) taking its fuell cell (and the Reuters viewers) for a ride. The real scandal is not so much the deception, but that the journalists fell for it.
