Electronic devices basically rely on electricity generated from a socket in the wall or an attached battery to power its functions. However, the reliance on these power sources limits them from being ideal for certain situations. These devices won’t be able to work in places where there are no power outlets. It is also inconvenient and sometimes risky to have to keep replacing or recharging the batteries of devices, like electronic implants, which are not within reasonable access. This is where biofuel cells come in.
