Yes,
Fuel cell technology is advancing. There is still the question of cost. There are some forklift manufacturers and companies using fuel cells instead of batteries. Pump it up with some hydrogen please! Keep in mind that these setups are basically a 1 12 volt power supply. You still need battery banks and inverters same as you do with Solar. However the battery capacity can be much less with 24 hour charging availability.

Subject: Friday - fuel cell battery charging

I was down at one of the docks today getting a tender support from from an expensive fancy boat ( Cabo something) and I stopped at the office where they had a display for fuel cell battery chargers

I had no idea this was a thing. Oh boy it looks good but lord knows the price of them. It's a big large, not super large mind you, for our vans, but I'm betting someone sometime will pop on in instead of solar.
