In this paper, a prototype of methanol microfluidic fuel cell with vapor feed anode configuration is proposed to improve the fuel and energy efficiency of the conventional liquid feed methanol microfluidic fuel cells. Peak power density of 55.4mWcm−2 can be achieved with this prototype under...

Laminar flow-based fuel cell (LFFC) is a relatively new type of fuel cell that does not require the use of proton exchange membrane. While the first-generation LFFC uses dissolved oxygen at the cathode, the second-generation LFFC (2G-LFFC) adopts a more advanced air-breathing design for...

A numerical model for a microfluidic electrolytic cell (MEC) for CO2 utilization and fuel production is developed and validated against experimental data in literature. Mass transfer and electrochemical characteristics at the cathode of the MEC are studied. Limiting factors to the cell...

Liquid fuel cells operated at room-temperature are promising candidates for the next-generation of power sources for microelectronic devices. Enabling high-concentrated or even neat fuel operation of fuel cells, which is currently limited by adverse fuel crossover through membrane, could...

This paper reports a theoretical investigation on the orientation-dependence of the performance of membraneless microfluidic fuel cell (MMFC) and the relevant gravity effects. A coupled computational fluid dynamics (CFD)/electrochemical model is used for the analysis. The results show that...

This paper presents a model integrating computational fluid dynamics (CFD) with electrochemical kinetics for predicting the performance of laminar flow-based fuel cell (LFFC). In the modeling analysis, we study the effect of parasitic current caused by the mixing of fuel and oxidant under...

The aluminum energy conversion processes have been characterized to be carbon-free and sustainable. However, their applications are restrained by aluminum production capacity as aluminum is never found as a free metal on the earth. This study gives an assessment of typical aluminum-based energy...

This paper advocates a modification of the impact-based approach to strategic environmental assessment (SEA) which seems unable to address institutional weaknesses in most conventional SEA cases in China. It identifies a possible alternative approach, i.e. an impact-centred SEA with...
