Figure 10 Evolution of fuel cell bus availability and some international targets (by 2015).
Bus availability is defined as the percentage of days of actual service compared to the
number of day of scheduled service over the year. The ratio should exclude downtimes
for planned maintenance 9

Figure 11 Evolution of the fuel cell bus range in comparison with some international
targets (by 2015). 95% confidence limits are shown where data were available.
9 This is compatible with HyFLEET:CUTE’s availability definition: “the ratio of time buses were
not in maintenance to the total timeframe of the project operation expressed as a percentage”.
