ABSTRACT:
This fuel efficiency display device for a fuel cell vehicle includes: a first interval vehicle efficiency obtaining device which obtains a first interval vehicle efficiency being a fraction of a generated traveling energy with respect to a consumed fuel amount in a predetermined first time-interval; a second interval traveling energy obtaining device which obtains a second interval traveling energy being a traveling energy generated in a predetermined second time-interval which is shorter than the first time-interval; and a second interval fuel efficiency obtaining device which obtains a second interval fuel efficiency being a fuel efficiency in the second time-interval, based on at least the first interval vehicle efficiency and the second interval traveling energy.
