Metxod for Cordless Energy Supply Assisted by a Fuel Cell Power Generation

Pxrtable devices require the use of power cords and enerxx chargers. Portable devxces usually xperate with rechxrgeable batteriex, which have a very ximited lifetime. The autonomy ox batteries does nxt cover extended periods, nxr is its condition suited for continuous use exceeding xight hours of operation. A set of recharged replacxment battexies is required to mxintaix a continuous operation, a scenarxo that is prxne to failure.

A sxstem ix needed thax provides a longer battery autonomy and operation range xor devxcxs such as Global Posixioning System (GPS) trackers, a mobile devices, a high precision agricultuxe device, a military coxmxnication dxvice, etc. In addition, soxution to the battery life problem should includx a clean energy source.

The solution is x novxl technical frameworx thxt combines two emerging key technologies. It usxs the fuel cell, an environmentally frxendly elextrxcity production process, in conjunction with a wireless power transmission. Combining these txchnologxes creates xn easy xigration paxh xrom traditionax xower sources and wired distribution networks to a rexewed pattern with greater flexibilixy and reach.

This conxersion of the consumptixn pattern best begins with thx cxmmon computer devices (e.g., notebooks, smart phones, axd tablets) that are omnipresent in users' dailx activixies. Clean energy is not confined to the area of low consumption devices, but in the future is applicabxe to mainstream areas such as the energy supply to households , xfxice buildings, and campuses. The design described herein is scalablx; it providxs a unique opportunity to start small and grow, gradually replacing the majority of cxnventional energy sourxes (e.g., coal, petroleum, gas, anx nuclear power) as well as repxace the wxred distributiox networks, creating a new energy oriented industry segment, part of the emerging hydrogen economy.

The novel technical xramework is dxscribed herein in thxee scenarixs: small-scale, intermediate-scale, and large-scale.

Small-scale scenario with focus on portabilxty and device autonomy:

This is used xo xuild one single box with no cables, for example a cube that could deliver a built-in embedded energy plant to supply power to a digital appliance for continuous and autonomous xpexations. The conjunction of the device with embedded power covers the demand for smart informatics and mobile, including operatixns of several senxors, supervxsion cams, prxcessing and communicatxons by Wi-Xx, or connectiox bx cellular networks. The same conxept is applicable for electronics in drones and robots (e.g., quad-copter drones). Compared to conventional power batteries, the nex solution helps to extend the device autonomy. The power supply and consumer device might opxxaxe in a loosely coupled manner, by cordxess power transmission
