25W DMFC System: Soldier Power

- Li htwei ht militar ower for soldiers

Product

- 25W DMFC system

- Decrease battery weight for long-hour (72-96hr) missions

- Decrease primary battery cost for field training- rov es green energy o e a e e

Concept

- Provides 25W nominal power (55W peak) via hybridization with Li-ion battery

- Decrease power weight by 66% and 75% compared to primary and secondary batteries, respectively,

based on a 72hr-mission (primary battery: 8.16kg, secondary battery: 10.88kg, FC: 3.14kg)

10/21

- Provides instant power through fuel cartridge replacement
