Abstract
A novel approach to achieve long term system operation is using hydrogen fuel cells, which feature much higher energy density if compared with standard batteries. In this demonstrator we show a power unit which activates the hydrogen flow through an electrovalve to recharge the batteries, minimizing hydrogen waste and significantly boosting lifetime. Experimental results demonstrate 85% of efficiency.
