How do you power a cyborg?

In this answer about how to design the ideal cyborg, I said:

...

• Use electric tissue to power the machines. Cyborgs need some way to generate electricity when mechanical parts are involved. Rather than batteries, which can corrode and leak, generators, which are noisy, or charging, which isn't always an option, consider a polymer layer below the skin that turns chemical energy into electricity. Polymers solve everything.(™)

I reasoned that while installing such a layer would be invasive and somewhat painful, it would work in all locations, and would not need to be refueled in the traditional way.

The cyborg in question needs minimal power - to aid locomotion a bit, to maintain an artificial heart, and to maintain a series of pumps throughout the body.

Is this an efficient way to power a human cyborg?

What alternative technology could do the job better, assuming charging / refueling cannot happen frequently?
