Fuel cells
Fuel cells have undergone intensive further development in recent years and have become a real alternative in self-sufficient energy supply.
This fuel cell, operated with a special water / methanol fuel cartridge, charges a battery connected to it via a built-in charge regulator. If this is full, the device switches off. If the battery voltage falls below a threshold value, the device switches on again and recharges current.
An inverter is also required for a 230V voltage.
A fuel cell works silently. During operation, waste heat, water vapor and CO2 are generated.
