There will no more be practical fuel cell cars by 2026 than there will be practical fusion power. Nor by 2030. Nor by 2040. Perhaps not ever.
If we can harvest hydrogen from the ground then it would take away from the cost of production, but I still don't think we could harvest enough to make it a viable replacement for ICE. If it is going to be a niche product then there is no incentive to build out the infrastructure. Chicken and egg.
However, mined hydrogen might be a good fuel source for energy production.
A neighbor's son is involved in a fuel cell research effort at school in conjunction with a commercial company. Their target is long haul trucks. They're large enough to handle the large footprint needed for hydrogen storage and for keeping it at a safe distance from fuel pumps, batteries, and so forth.
That's an interesting option.
