Abstract
This paper reports on the strategy to increase the performance of the totally integrated light driven μ-fuel cell device (Fig.1), which was developed by our group [1] by optimizing extended-nanochannels (ENCs) length in μ-fuel cell device. The fabricated device based on optimized ENCs parameters showed 3.3 times improvement in comparison to our previously reported μ-FC device. This work will contribute to development of portable power generation device.
