A key requirement of fuel cells for heavy duty vehicles is lifetime in operating hours. As examples, a bus will do 5000 hours per year and have a lifetime of 15 years and a refuse collection vehicle 3000-4000 hours a year and a 10 year life. This can be achieved through a combination of design for long lifetime, operating mode and replacement or refurbishment aiming to minimise total cost of ownership.
For road vehicles power requirements are in the range of 50kW-200kW
The survey asks about interest and capabilities for current technology and the R&D requirements to develop improvements on the current state of the art for complete fuel cell modules and key components such as air compressors and fuel cell stacks.
