A paper based fuel cell, which uses capillary driven pumping (because of porous fiber network present on its surface) to pump the fluids. Unlike traditional fuel cells, the paper based fuel cell works on self-pumping and self-breathing mode with low consumption of the liquid fuel and electrolyte to generate energy for very long time. The novelty of this device is that the fuel flows through capillary transport mechanism without use of an external pump and the oxygen is obtained through the porous pencil stroked graphite electrodes from quiescent air. The developed micro-fuel cell produces power density of 32 mW/cm2 with potential up to 330 mV. The fuel cell can have several potential applications having low energy requirements.
