I can't speak for your experiences, but finding a place to certify to 10k psi I found to be really difficult, and AFAIK, places won't fill unless you have a recent cert.

IIRC Ford did at least one plug-in FCEV prototype when Bush Jr. was still the POTUS. Well, nowadays I'd not hold my breath for something like that to become mainstream. Even some plug-in serial hybrid with a multifuel microturbine-driven "range extender" would be more likely to reach commercial viability under a mass-market perspective than a fuel cell.

A Fuel Cell isnít the real problem

Itís the hydrogen part.

Nissan was testing an alcohol powered fuel cell range extender on its EV van

That is the correct way if there is any

The fuel cell is the problem.
Right now it takes about a troy ounce to build a car fuel cell. Yeah bostitch says they are working on a 7gm of Pt fuel cell but I wouldn't hedge bets on it.
Pt, Pd are constrained resources. There isn't enough for everyone who wants a car to have an ounce of Pt.
Long term forecast in the mining industry says in 10 years current usage for catalytic converters and oil refinery wont be kept up with then by 20 years there will be shortages.
Add a demand of tons more for fuel cells and no.
The reason why they want to attempt to build a 7gm of Pt fuel cell is because that's about how much is in a larger catalytic converter then it could just be a roughly 1:1 swap, not a 4:1 swap.

Lead and manganese can power an ethanol fuel cell

I think liquid fired fuel cells make way more sense but that's not where the industry is going.
All the gooberment and private research money is for hydrogen fuel cells.

That's why fuel cells never caught up. Trying so hard for an approach that looks far more sophisticated, and in fact it is, has a price the average Joe is not willing to pay and maybe can't actually afford. Durability of the membranes of a fuel cell and some eventual difficulty to recondition them, while it may seem easier to overhaul a traditional ICE, are also likely to be a deterrent against FCEVs.
