“…The results obtained in this study not only demonstrate the feasibility of the device but also give a guideline for design and condition optimization. [43][44][45][46][47][48] Kamitani et al [53][54][55] demonstrated a state-of-the-art room temperature operation of the silicon microchannelbased μDMFC with a very high fuel use efficiency of 75.4%, operating at an output power density of 9.25 mW/ cm 2 for an input fuel (3M aqueous methanol solution) flow rate as low as 0.55 μL/min. An output power density of 12.7 mW/cm 2 was also observed for a fuel flow rate of 2.76 μL/min.…”

Most people were not aware of the role of energy as a basic force that drives the development and economic growth of the world until the two great oil crises occurred. According to the conservation law, energy not only exists in various forms but is also capable of being converted from one form to another. The common forms of energy are mechanical energy, chemical energy, internal energy, electrical energy, atomic energy, and electromagnetic energy, among others. The fluids in nature serve as the most common carriers and media in the energy conversion process. Following the rapid development of microelectromechanical systems (MEMS) technology, the energy supply and conversion issue in micro/nano scale has also been introduced in research laboratories worldwide. With unremitting efforts, great quantities of micro/ nano scale energy devices have been investigated. Micro/ nanofluid shows distinct features in transporting and converting energy similar to their counterpart macroscale tasks. In this paper, a series of micro/nanofluid-enabled energy conversion devices is reviewed based on the transformation between different forms of energy. The evaluation and contradistinction of their performances are also examined. The role of micro/nanofluid as media in micro/nano energy devices is summarized. This contributes to the establishment of a comprehensive and systematic structure in the relationship between energy conversion and fluid in the micro/nano scale. Some fundamental and practical issues are outlined, and the prospects in this challenging area are explored.

“…The silicon-based BPP has very low electric conductivity. On the other hand, silicon microfabrication techniques, such as reactive-ion etching [9], photolithographic masking and deep reactive ion etching [10], nanoimprint technology [11], are time-consuming and costly. Recently, more and more researchers have been focusing on graphite composite bipolar plates (GCBPPs) [12−14].…”

A new method of manufacturing micro-flow channels on graphite composite bipolar plate (GCBPP) microplaning using specially designed multi-tooth tool is proposed. In this method, several or even dozens of parallel micro-flow channels ranging from 100 μm to 500 μm in width can be produced simultaneously. But, edge chippings easily occur on the rib surface of GCBPP during microplaning due to brittleness of graphite composites. Experimental results show that edge chippings result in the increase of contact resistance between bipolar plate and carbon paper at low compaction force. While the edge chippings scarcely exert influence on the contact resistance at high compaction force. Contrary to conventional view, the edge chippings can significantly improve performance of microfuel cell and big edge chippings outperform small edge chippings. In addition, the influence of technical parameters on edge chippings was investigated in order to obtain big, but not oversized edge chippings.

“…Using silicon for the microfabrication of MFCs has two advantages: readily available mature microfabrication techniques, and the integration of the device with the rest of the microelectronic circuitry [2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

“…Unlike the researchers listed above, Kamitani et al [13][14][15] integrated commercial macroporous and microporous layers into their silicon MFCs. The commercial micro-and-macroporous layers were placed on top of the silicon flowfield, but the electrical contact between flowfield and GDL was irrelevant, because in their set-up the flowfield was not a current collector; the authors used a gold mesh inserted between the flowfield and the GDL to collect the current.…”

Abstract:We have integrated carbon felt, a traditional fuel cell gas diffusion layer, with silicon micro fuel cells. To this end we used two silicon microfabrication procedures using reactive ion etching: formation of black silicon and sinking of flowfield. The former decreases electrical contact resistance to the diffusion layer, the latter serves to contain the reactant gases. The micro fuel cells, where the flowfield was covered by black silicon nano-needles, showed better performance (127 mW cm -2 ) compared to the same cells without black silicon (114 mW cm -2 ). The black silicon fuel cells were also more stable during an overnight chronoamperometric measurement.
