Furthermore, Ballard is abandoning hydrogen fuel cells in favor of methanol fuel cells, and methanol is not as energy dense as formic acid. Also the MVTG formate fuel cells cost about 20% of what Ballard and Plug and Neah power fuel cells cost to build, because MVTG is the first to build a successful fuel cell that eliminated the need for the very costly Nafion DuPont membranes (that fail too easily) and bi-polar electrode plates, that run the cost up 500% above the new MVTG fuel cell designs that are patent issued now.
