Micro Direct Methanol Fuel Cell (μDMFC) has been a promising new type of portable energy device due to its high energy density, quick start features and simple operation environment. Water management is one of the most crucial problems for hindering the development of passive μDMFC. A novel cathode structure of passive μDMFC controlling water management and increasing methanol concentration is proposed...
A novel water management system for micro passive DMFC is fabricated and characterized in this paper. This system consists of both a cathode current collector made of a 316L sintered stainless fiber felt (SSFF) and an aluminum-based end plate fabricated with a perforated flow field. Besides, some water-collecting channels were fabricated on the surface of the cathode end plate and then covered by...
In this paper, a μDMFC (micro direct methanol fuel cell) with high performance was fabricated by adopting aluminum alloys as a substrate for the first time. PEO (plasma electrolytic oxidation) was adopted to prepare an oxide coating on the substrate to make it electrically non-conductive and corrosion resistant. The PEO-treated substrate shows excellent corrosion resistance in the simulated DMFC environment...
To solve the water flooding problem of micro passive direct methanol fuel cell (DMFC), plasma electrolytic oxidation (PEO) was adopted to prepare a superhydrophilic coating on the surface of an aluminum-based cathode current collector which contacts with air. Results data show that liquid water spreads quickly as a plane on the surface of the porous PEO coating that is composed of Al 2 SiO...
