Evaluation of a Hydrogen Powered Scooter Toy Prototype
Nov 2022
Publication
Electric scooters are used as alternative ways of transport because they easily make travel faster. However the batteries can take around 5 h to charge and have an autonomy of 30 km. With the presence of the hydrogen cell a hybrid system reduces the charging times and increases the autonomy of the vehicle by using two types of fuel. An increase of up to 80% in maximum distance and of 34% in operating times is obtained with a 1:10 scale prototype w Read More
