Your home based fuel cell

About a year ago, I mentioned how Japan has some homes that use fuel cells to generate electricity.

Here's another article about it. This is surprising:

The Japanese government is so bullish the technology it has earmarked $309 million a year for fuel cell development and plans for 10 million homes - about one-fourth of Japanese households - to be powered by fuel cells by 2020.

They work by extracting hydrogen from natural gas, to which lots of houses in Japan are connected. I wonder if they would be better if hydrogen was stored on site, in one of those new storage systems that seem promising.
