Abstract
In this work, we report on the development of a micro fuel cell device (MFC) (free of the proton exchange membrane (PEM)) on a fused silica microfluidic chip platform where a new approach to utilizing extended-nano channels for efficient proton transport and separation has been realized. Experimentally we detected that a small amount of Pd components (∼10 wt.%) is the best concentration for the anode material operated at the room temperature. Also we detected efficiency improvement of the present MFC when changing the nanochannels' number and size. With the device operated at 25°C, the maximum power output was recorded at ∼25 μW/cm .
