I expect you are thinking of hydrogen. It's not that we don't have plenty of ways to make it, indeed we do that, in vast quantities, to manufacture fertilizers, margarine etc. The problem is that we make it from natural gas, a fossil fuel, and there's no point to the fuel cell if it doesn't replace fossil fuel use. We can also make hydrogen by electrolysis, but that requires electricity, and therefore a way of making electricity, so doing that without burning fossil fuels becomes the issue.

This lack of availability hinders the widespread adoption of fuel cell vehicles.
