Fe‐N‐C catalysts show great potential to replace Pt/C in oxygen reduction reaction (ORR). Polyaniline (PANI) is an ideal precursor with an abundant and homogeneous distribution of nitrogen sources. However, Fe‐N‐C based on PANI suffers from an unsatisfied performance in acidic media. Herein, a facile zinc‐assisted synthesis of Fe‐N‐C based on PANI was reported in this paper. ZnCl2 templates can be...
In order to overcome the disadvantages of low mass transport efficiency of oxygen to the cathode and poor performance of passive micro direct methanol fuel cells (DMFC), the structures of the cathode current collector for the passive micro DMFC have been studied. The passive micro DMFC employing the cathode current collector with the planar perforated-plate structure has been fabricated. The effect...
Design and fabrication of a silicon-based micro direct methanol fuel cell (μDMFC) are presented in this paper, and a novel encapsulating method adopting PDMS is also designed, which could easily achieve close contact of the critical cell components. Meanwhile, serpentine flow field is found to have the optimal performance by different flow field structures of μDMFC tests, and the optimized size of...
In this paper, an active oxygen-supplying micro direct methanol fuel cell (μDMFC) and an air-breathing μDMFC were designed, fabricated and tested. Stainless steel plates with the thickness of 200μm were chosen to fabricate the current collectors by the micro stamping. The 5-layered membrane electrode assembly (MEA) was fabricated by the catalyst coated membrane (CCM) method. The polymethyl methacrylate...
Based on CFD (computational fluid dynamics), modeling and numerical simulation of the muDMFC (micro direct methanol fuel cell) are carried out ,meanwhile the influence of the muDMFC with various flow channels design is studied using the CFDRC commercial code. The simulation results show that the performance of the muDMFC with the parallel flow field excelled the one with the dot flow field. The experimental...
The design and fabrication for a novel silicon-based micro direct methanol fuel cell (mu-DMFC) of 0.64cm2 active area on <100> silicon wafer are described in this paper. The novelty of the DMFC structure is that the anodic micro channels arranged in the asymmetric mesh have been fabricated, and the first objective of the experimental trials is to verify the feasibility of the novel structure...
