Fuel cells may still find their niche such as stationary storage. If it doesn't need billions of dollars in infrastructure, like a hydrogen powered vehicle would need, then hydrogen fuel cells may be well suited for that application. Splitting water via electrolysis, storing the hydrogen, then "burning" the hydrogen in a fuel cell to create electricity again seems like a good idea for applications where the power would be wasted anyway. The best scenario I see would be large wind farms. I don't see a practical application for household usage. So in the end fuel cells will remain a niche industry and I still think Samsung is right to remain focused on batteries. That's where all the money will be going in the coming decades.
