Fuel cells from Germany

摘要

Energy is another major issue for all soldiers, especially those on foot, and fuel cells are becoming a valid problem. At DSEI 2013 SFC Energy from Germany introduced its latest product, the Jenny 1200, that joins the Jenny 600S as portable energy source for patrols. Compared to the previous model, it doubles all the data in terms of nominal power, 50 W versus 25 W, maximum charging power per day - 1200 W versus 600 W hence the designation - and weight, 3.12 kg versus 1.6 kg. The Jenny 1200 runs on pure methanol contained in four fuel cartridge sizes (350 ml, 2.5, 5 and 10 litres weighing 0.371, 2.2 kg, 4.3 and 8.4 kilos with nominal capacities of 400 Wh, 2.77 kWh, 5.5 kWh and 11.1 kWh). For the time being measuring 214 × 96 × 264 mm the Jenny 1200 is in its last stages of development and all given data may change. According to SFC Energy the use of 100% methanol dramatically increases energy density compared to methanol/water blend fuel cells.
