Integration of silicon micro-hole arrays as a gas diffusion layer in a micro-fuel cell

The experiment yielded results for 10 μm, 30 μm and 50 μm micro-hole arrays, for various fuel flow rates and under various operating conditions. The maximum power density was approximately 8.13 mW/cm2 with H2/O2 gas flow rates of 30/30 ml/min and 10 μm micro-hole arrays at 20 °C.
