No. Just no. There are a multitude of reasons, not limited to: change in hazardous area classification, different fuel nozzle design, heat of combustion temperature issues and thermal efficiency. Fuel cells are around 94% efficient while the best practical combined cycle is around 55%.
If you have hydrogen, the best and most efficient way to turn that into electricity is a fuel cell.
The issue is always, where do you get the H2?
If you have CH4, the most efficient way to convert that to electricity is a combined cycle gas turbine. By the time you get it to hydrogen, you will have lost a bunch of the energy, even with going to a fuel cell.
