PROBLEM TO BE SOLVED: To early detect aged deterioration of fuel supply means 19, 20 and prevent increase in NOx emission amount, in a hydrogen fuel supply device supplying hydrogen fuel to a hydrogen engine 1. SOLUTION: A deterioration determination means 54 sets deterioration determining supply amount determined by adding predetermined addition amountΔF to target fuel supply amount Ft determined in accordance with an operating condition of the hydrogen engine 1, makes the fuel supply means 19, 20 perform hydrogen fuel supply based on the deterioration determining supply amount, and determines that the fuel supply means 19, 20 are deteriorated when NOx emission amount exceeds a predetermined determination value due to the hydrogen fuel supply.
