Dougster, from what I have gathered over the last two years concerning Hydrogen cells, they still take pure liquid Hydrogen as a fuel correct? Heck most urban areas with surronding homes and schools cringe at the thought of a 1000 gallon main fill tank in the neighborhood. Also the support infrastructure is just not there yet at the local levels for customers to make viable decisions on the long term effectiveness of these systems. Do they work? Yes. Are there landmines and pitfalls associated with them? Yes. Is the ROI acceptable? I would have to say no at this point in time.
