All else being equal, which is preferable and why? 2 220 AH 6v batteries or 2 110 AH 12v batteries

Other than the disadvantages of small volume producton, I wonder why fuel cells are so expensive .... each one hand assembled by engineers .... or the materials are found only on Venus? :h and :E
Yes they use rare Earth catalysts that are basically manufactured in a lab in small batches. There's also very expensive intellectual property involved, the folks that patent the technology don't want it mass produced.
Bloom Energy mass produces a hydrocarbon fuel cell. Fuel from propane, methane, etc. The fuel cells are huge though.
