Portable SFC fuel cells – Applications: Observation Troops 

Mission: a forward observation troop, mortars, with a PLGR 95 PPS. Devices deployed:

• GPS navigation device: operating time - 48 hours; power consumption: eight AA batteries (NBA 3058, 32g apiece) every 90 minutes.
• Fire-control computer (MRT 86): operating time: 48 hours; power consumption in continuous operation:  1 mono battery (144g a piece) per hour.
  Using only batteries
• In order to power the navigation device for 48 hours, a soldier would have to carry 256 batteries on him for a total weight of 8.2 kg. 
•  In order to power the fire-control computer for 48 hours, a soldier would have to carry 48 mono batteries on him for a total of 6.9 kg.

=> In order to power these two devices alone, a soldier would have to carry 15.1 kg worth of batteries on him.

Using the JENNY 600S fuel cell In order to power both devices for 48 hours, a soldier would only have to carry

• one JENNY 600S (1702 g),
• three fuel cartridges (1146 g altogether),
• a charging device (approx. 600 g),
• 16 AA rechargeable batteries (512 g)
• 12 mono rechargeable batteries (1700 kg).

The total weight of the above amounts to a mere 5.7 kg.  

=> Using a JENNY 600S-type fuel cell permits a weight reduction in this case of 63%.

What’s more, there is still capacity to supply other devices. If one were to exploit the JENNY to its fullest, it would be possible to reduce weight by up to 80%.
