Dependent on duty cycle. LHV=Lower Heating Value & represents the energy available in hydrogen fuel. To compare, diesel engine efficiency is typically ~20%. Fuel cell system efficiency will be lower than stack efficiency because of parasitic losses – expect an additional 5-10% loss in efficiency. For hydrogen applications, Ballard recommends hydrogen purity of 99.99% or better.
