Hmm, isn't it 170 liter tank inside, not the shell? I thought 70MPa 170l tank would have 119K liter of H2 nominal...??
It is a hydrogen storage volume of 171 litres.
The outside shell is extra
alternatively Hydrogen tank capacity is 171 litres.

so the outside shell is extra
If the calculations are done in reverse, starting with a Tesla, making a Tesla in a Hydrogen configuration would reduce range.
I suspect Hyundai's pricing is more realistic than Toyota's and Hyundai prices their HFCV in Korea at about US $145k (before a $60k Korean Government subsidy)
Korea's government subsidy makes Japan's Hydrogen subsidy look paltry.
back to the costing approximation, the H2 tank/Li ion anode both supply the 'fuel' for the cathode/fuel cell
if the li ion anode is cheaper than the H2 tank and looks set to remain that way forever (no crossover)
and if the li ion cathode is cheaper than the platinum fuel cell and looks set to remain that way at desirable power levels forever (no crossover)
then the only way for HFCV to be cost competitive is for H2 to be cheaper than electricity to the extent it can subsidise the H2 Fuel Cell and tank. Which is highly unlikely. forever
there is a trend for hydrogen fuel cells to get cheaper, but the end price point is still more expensive than Li ion BEV.
There is also one more key aspect.
Markets are not democracy.
Democracy - one man - one vote. The people without their own parking may expect 'their' subsidy to go to a technology that appears to continue filling up away from home.
The Market, the new car market, the more expensive the car, the greater the occurrence the owner has their own parking.
The market growth will continue to favour BEVs, Hydrogen vehicles will attract massive government subsidy in many jurisdictions, but disappoint in demand.
In a way both hydrogen and brown coal are similar, that is they are low grade fuels compared to their counterparts (H2 vs CH4 and brown coal vs black coal)

perhaps I misunderstood you.
for volume
the inside an 18650 battery is called a jellyroll (named after a similar looking piece of food). The jellyroll can be compared to the inside volume of a H2 tank.
The outside of a 18650 battery is what is comparable to the outside of a H2 tank.
yes 70MPa 170l tank would have 119K litre H2 atmospheric, but what is modelled is how many miles can a comparable vehicle run per unit of car space taken up by the 'fuel tank'.
