Apple may be among the top tech companies today, but its struggle to keep its devices powered and running for a long time is no secret. Now that a patent filing has been leaked to the Internet, it is possible that the Cupertino tech giant may have already solved its problem.

Since the company launched its gadgets, it has been finding ways to keep them on longer. Based on what was indicated on Free Patents Online, Apple may have applied for a patent for a fuel cell system that will be used for powering a "portable computing device."

According to Tech Times, the application's clear reference to the MagSafe connector could only mean that the fuel cell battery that Apple might be working on is intended for MacBook.

Such new feature might be a breakthrough in today's technology, but Apple's decision to use fuel cell batteries will most likely be met with both positive and negative reception from the masses.

With a fuel cell battery, Apple MacBook users could use their laptops for days - maybe even weeks - without having to recharge the device. However, it must be noted that using such system would mean that the device will be bulkier.

This detail is most likely going to be looked down on, considering that tech companies today are competing against each other to make thinner laptops. In fact, Intel has just released its much-awaited 14nm Skylake M processor.

The idea of using a MacBook with a fuel cell battery might be intriguing, but it reportedly looks like its target market will be those who tend to do computer-related work in the outdoors, such as during camping trips or forest cabin vacations. So far, these reports have not been confirmed by Apple, so it's best to take the info with a grain of salt.
