چکیده

This paper presents a silicon-based micro direct methanol fuel cell (μDMFC) stack with compact stacked structure and a unique shared anode plate. The μDMFC stack consists of two fuel cells in electrically parallel connection, while the fuel transport is arranged in series. Experimental results show that the μDMFC stack generates a power density of 12.71mW/cm, almost twice as much as that of a single cell, when fed with 1M methanol solution at room temperature.

A monolithic integrated micro direct methanol fuel cell based on sulfo functionalized porous silicon

In this paper, we demonstrate a monolithic integrated micro direct methanol fuel cell (μDMFC) for the first time. The monolithic integrated μDMFC combines proton exchange membrane (PEM) and Pt nanocatalysts, in which PEM is achieved by the functionalized porous silicon membrane and 3D Pt nanoflowers being synthesized in situ on it as catalysts. Sulfo groups functionalized porous silicon membran...
