This project looked at hydrogen fuel cell electric cars to see how well they work in real life and how the technology is improving. The researchers wanted to check if these cars can meet the set targets and market needs. In 2018, they studied how far these cars can drive, how efficiently they use fuel, and how easy it is to refill them with hydrogen. The main findings show that these cars can go long distances, use fuel effectively, and get refilled easily. The research helps guide future developments in hydrogen technologies for cars.
