How do you think the hydrogen is produced? Currently it's either a product of petroleum or produced by using electricity to split water. So your argument of electricity not inherently being clean energy applies to hydrogen as well.

Assuming you use electricity to split water to power your fuel cell, you've basically just made an even more complicated way to use electricity to power your car. So at that point, just simplify it and just use a battery and a motor.

Small nit to pick, its produced more from steam reformation of methane:

"There are four main sources for the commercial production of hydrogen: natural gas, oil, coal, and electrolysis; which account for 48%, 30% 18% and 4% of the world’s hydrogen production respectively."
