However, as a major component of natural gas, it is often mixed with other gasses that do smell, so it gets a bad rep. Pure methane in a fuel cell gives off CO2 and water vapour (which could threaten the electronics?). Recharging it should be as simple as injecting a fresh charge of methane. Since methane can be acquired from biogenic sources, there should be no net increase in greenhouse gasses using this technology. The good news (I hope) is that no heavy and toxic metals are needed, so disposing of worn out cells should not result in toxic waste.

didn’t work at all. I recharged a battery overnight and the next morning, the battery
lasted 5 minutes 🙁 But going back to using methane as a fuel source, often we see
waste sites that will collect the gas produced from waste and reuse it to heat buildings.
It does have potential…
