This fuel cartridge used in the MiniPak has a battery-like form factor and contains a special metal alloy that allows hydrogen to be stored in a solid-state, as part of the metal alloy matrix inside the cartridge. In contrast with ordinary compressed hydrogen tanks, the pressure inside the canister is very low, making this device the safest and most practical means of storing hydrogen. The HydroStik has the additional advantages of being refillable (from pressurized gas bottles, or from water-electrolysis based devices like the Hydrofill fueling station), non-toxic, eco-friendly, and competitive on cost/performance with existing battery devices. Each HydroStik can store 15Wh of energy, enough for 1-2 charges of a 3G smartphone, or 2-3 charges for average cellphones, which is more than what present primary and rechargeable batteries are able to offer at equivalent cost.
There are other ways to fill up the Hydrostik catridge without needing the Hydrofill fueling station, please see the User's Manual for more details.
IMPORTANT CLARIFICATION: 1 HydroStik = 10 disposable AA batteries at 1W continuous power consumption. This is because at 1W power consumption, most AA batteries can only last one hour, while the HYDROSTIK has enough energy to last 10 hours. If one HydroStik is then refillable 100 times, the same HydroStik can replace 10x100 or 1000 disposable AA batteries over its lifetime, including multiple refills when the required continuous power is 1W.
