Let's grant your point about prices coming down, and let's say that a fuel cell, a small battery, and the fuel tank(s) is the same price or even cheaper than a BEV. Let's just take that as completely granted.

How about the cost of energy per kWh? Hydrogen is much more expensive than just buying the electricity. In Norway, right now, price of H2 is 195 NOK/kg or about $19.13 USD per kg. 1kg of H2 is 33.33 kWh, meaning it's about $0.574 USD per kWh for hydrogen. Even the most expensive DCFC don't sell for that price. Here in the US, the production costs alone, as reported by NREL, are well above the cost of traditional fuel and electricity based on using methane cracking with steam assuming we can make that commercially viable. Cracking the methane is much more expensive than just burning it to produce electricity, and that doesn't account for increasing nuclear or renewable energy sources on the grid.

On a per-kWh basis, a hydrogen fueled car will necessarily be more expensive to refuel than a BEV, while battery costs continue to decrease just as fuel cell costs have.
