Summary

The paper and presentation will offer a comprehensive examination of the integration of fuel cell technology into the heavy-duty vehicle sector, positioning fuel cell electric vehicles (FCEVs) and battery electric vehicles (BEVs) as synergistic solutions for achieving net-zero objectives. The paper underscores the substantial investments made by OEMs in developing alternative fuel, internal combustion engine-hybrid, and BEV platforms. FCEV power systems exhibit performance parity with conventional powertrains, and for many heavy-duty vehicle applications they are the only practical zero-emission solution. The paper also delves into the economic and technical barriers that have historically prevented wider FCEV adoption.

The advantages and limitations of BEVs and FCEVs are contrasted, considering factors such as efficiency, payload, range, and refuelling. Improvements in power density and longevity of heavy-duty fuel cell modules, through Ballard's continued technological leadership in advanced membrane electrode assembly design and balance of plant optimisation, are also explained. Furthermore, a holistic approach to fuel cell integration is discussed, encompassing the importance of hybrid DC-source rightsizing (with real-world examples), thermal management, and standardisation of systems and assemblies. The paper highlights the importance of an FCEV design approach. Both to positively impact the TCU by right-sizing components and improving efficiency and to minimise integration challenges with accurate modelling and system standardisation.
