$MVTG , Here is a good article showing the superiority of using fuel cells for power backup over batteries, diesel generators etc...It is talking about Hydrogen fueled fuel cells. The drawbacks it mentions for Hydrogen FC's are the obvious: Very limited Hydrogen infrastructure, the volatility of hydrogen, the expense etc..
Could you imagine how much more glowing this article could be if it was talking about a fuel cell from Mantra?
Using the integration of Mantra's 2 novel technologies: Fueling the MRFC(mixed reactant fuel cell), not with hydrogen, rather with carbon neutral energy dense chemicals like formic acid and formates which is the product of Mantra's ERC technology.
The article wouldn't just be a positive endorsement for fuel cells for energy backup...it would be disruptive and game changing! MVTG
