The U.S. Patent and Hallmark Office has today released a patent application from Apple for a fuel cell system developed to allow a MacBook to operate without external power “for days or perhaps weeks.” The patent was released quickly after a British business rumored to be working with Apple handled to fit a fuel cell battery into an iPhone 6, powering it for a week at a time. We initially reported on that project last summertime.

While the patent refers only to a ‘‘ portable computing device,’ both the text and diagrams particularly reference MagSafe, giving a clear sign that a MacBook is the device in question (even if Apple might be moving far from the system) …… There is, obviously, no such thing as a totally free lunch, and fuel cell systems require the fuel to be replenished once it is exhausted, which the patent addresses by referencing detachable cartridges. Apple is

keeping its options open on the fuel made use of in the system. The fuel source makes up at least among: salt borohydride and water; salt silicate and water; lithium hydride and water; magnesium hydride and water; lithium borohydride and water; lithium aluminum hydride and water; aluminum hydride

; an amine borane complex; a hydrocarbon; lithium aluminum hydride; magnesium borohydride; a magnesium borohydride-amine complex; compressed hydrogen gas; and liquid hydrogen. The most likely implementation would be a mix of standard batteries and fuel cells, allowing the MacBook to be charged in the normal way, changing to sustain cell power just when extended cordless use is required. As constantly, we note that just a small percentage of the

things Apple patents ever make it into items, but I have to state that I truly hope this is one of them. Leading image: SlashGear Submitted under: AAPL Company, iOS Devices, Mac Tagged: Apple Inc, Fuel cell, Fuel cell battery, Fuel cell iPad, Fuel cell
