Read all about it. Samsung SDI Drops Hydrogen Fuel Cells For Focus On Batteries For Electric Cars | CleanTechnica
Nice find! Between failed Canadian hydrogen bus trials & this revelation, USB will have to find a ton of Toyota pro-hydrogen articles to counter Samsung's logical decision. We'll never be able to imagine how far along we'd be with battery development if so many billions hadn't been wasted on trying to make hydrogen less impractical over the past 4 or 5 decades. And yet hydrogen still only works for a teeny niche market. Maybe this decision will help Toyota grasp how foolhardy their their experimenting with automotive hydrogen is. Probably not. .
^Tesla entered their market, and they saw the light? Japan is still stuck on stupid (blame Fukushima).
