Direct fuel cell—supercapacitor hybrid power source for personal suburban transport

<abstract> <p>In view to proposing an alternative oversized energy sources currently installed in electric vehicles for suburban transport, a direct hybrid fuel cell (FC)-supercapacitors (SC) source has been designed and tested on test bench. The rated 15.6 kW source—with air-cooled 5.6 FC 165 F SC storage device—was shown perfectly suited traction of 520 kg vehicle along the NEDC cycle, then validating previously developed concept one-ton car propelled by 10 30 this cycle. In comparison with used alone, hybridization was allow power demand vary quite narrower range, as formerly observed. Moreover, rates voltage current generated driving were be reduced one order magnitude which is contribute durability. Two operating parameters have significant effect efficiency, namely capacity at 110 or F, recovery deceleration power—emulated external supply—which can decrease 25% consumption cycle conditions, predicted model.</p> </abstract>
