For the propulsion of an electric scooter, a PEM fuel cell stack has been developed at ECN which can run at atmospheric pressure and without the prehumidification of anode and cathode feed gas. Furthermore, the stack does not contain any humidification section itself.
Pure hydrogen is used as the anode fuel, air is used as the cathode feed.
The air-cooling is integrated in the stack With this stack, a system could be realised with a minimum of peripheral components and with a minimum of parasitic loss. At these conditions, the power output is in the range of 1100 - 1200 Watts. Currently a redesign is being carried out to make the stack liquid cooled and suitable for reformate gas.
