I believe this is done during the preparation stage.

Plus some hydrogen might be needed in a small tank, to be added as hydrogen slowly leaks out of the cell. That may not be needed. Recharging the cell once a year at a dealership might be sufficient. I do not know how gas-tight a cell can be. The tanks of pure hydrogen I have seen in laboratories sit around for years without losing pressure, as far as I know. In any case, the make-up gas tank would be very small, about the size of compressed air tanks used by bicyclists. Like this one that holds 600 mL, 16 bars max: https://www.amazon.com/SKS-RideAir-Portable-Air-Tank/dp/B01MCWGREM Which, if I have used an on-line calculator correctly, comes to 0.020 g/mL, or 12 g of air. Hydrogen weighs 7% of air, so that's 0.84 g. I think it would be easy to ensure that any gas leak goes into the atmosphere and does not enter the passenger cabin. Hydrogen is lighter than air and would quickly go out from under the hood of the engine compartment. The heat engine portion of a cold fusion powered vehicle would probably have low Carnot efficiency, so it would need a cooling fan. This could easily ensure any gas leak is blown away. (I say it would have low Carnot efficiency because keeping the temperature at a moderate level, such as 300°C, would prolong the life of the equipment, and there is no point to saving fuel by increasing Carnot efficiency.)
