Fuel Cell Electric Tractor FCTRAC: Vehicle Design and Architecture

Abstract

Sustainable agriculture demands alternatives to fossil fuels. The FCTRAC project adopts a circular economy approach, focusing on zero-emission solutions. A fuel-cell-powered electric tractor with 95 kW, derived from a diesel model (STEYR 4130 Expert CVT) was developed. It integrates key components such as a 700 bar compressed hydrogen storage system, fuel cell, electric drive, and high-voltage battery. Leveraging existing driveline technology minimizes costs and development risks of the project. The vehicle achieves comparable performance, optimal visibility, as well as single type approval for on-road usage. This paper details the vehicle architecture, design, and key integration challenges, advancing the development of zero-emission agricultural machinery.
