Fuel cell powered data centers could ultimately become buffers for the power grid relying on the grid mainly for backup power and even selling excess power back to the utilities. Fuel cells offer high efficiency and avoid the ~7% transmission losses for long distance electrical transmission lines, and importantly for data centers, local generation is not susceptible to all the disruptions of the power grid.
