A vehicle fuel cell system according to this invention comprises a controller
(20)
that compares a input running distance to a predetermined distance. When the input
running distance is less than the predetermined distance, the controller (20)
finishes running using only the hydrogen supplied from a hydrogen storage device
(14) without starting a start-up combustor (50). When the input running
distance is larger than the predetermined distance, the controller (20)
starts hydrogen supply from the hydrogen storage device (14), and simultaneously
starts warm-up of a reformer (3) by starting the start-up combustor (50).
When warm-up of the reformer (3) is complete, supply of hydrogen from the
hydrogen storage device (14) finishes, and hydrogen supply from the reformer
(3) starts.
