The main issue with the non hydrogen fuel cells is the efficiency.The problem with methanol and ethanol fuel cells is that their end products contain both water and carbon dioxide. CO2 is the air pollutant that causes global warming that we want to reduce at all costs. Another problem is the low efficiency of platinum catalyst when it's used in methanol and ethanol fuel cells, especially in ethanol fuel cells.
With hydrogen it is easy to reach 60% efficiency, but with anything else it will be less than the carnot cycle.
That is the reason why everyone try to push hydrogen.
For the safety issues, the battery charging incidents could be as good as anything.
Fukushima is interesting because insignificant amount of hydrogen could destroy complete buildings .
And not a bit, but doing very respectable damage.
