The new system generates 25kW of net electricity to support bus, light and heavy duty vehicle applications.

The company expects the system’s principal use to be a range extender for electric vehicles.

The modular design, which is based on Proton Power’s PM400 fuel cell stack, will produce 50kW or 75kW of energy in multi system applications.

Proton Power said the HyRange 25 system has the capacity to generate enough energy of an electric powered city bus for an entire day.

The heat generated by the system will support the heating system in the bus in order to increase the efficiency.

Proton Power CEO Nahab said: "Our HyRange 25 system with our own designed PM400 fuel cell stack can provide enough power for a 12 metre city bus.

"The world market for emission free transport in megacities will explode and the demand for emission free systems is growing dramatically.

"We offer industry leading expertise, know-how and customer support from the first simulation up to the final integration. I would like to congratulate and thank my team for this new development, fulfilling the project on time and within budgeted cost."
