Fuel cell technology has been around for some time now, what I don’t get is why its still not widely used in laptops and portable electronic devices.
If you can please briefly clarify
Please Help Me!
It is just not cost or space effective though, compared to the cost of a metal based chemical battery and accessory equpment. Not to mention it is not just quite convenient.

The fuel cell would have to be as huge as a cow. Would look silly attached to small laptop. No more portability.
