The study on a new method of preparing PMMA forming composite bipolar plate

Abstract

The recent oil resource shortage has prompted the development of the proton exchange membrane fuel cell (PEMFC) system. PEMFC is a possible source of power that can be used in aircraft, household electricity, agriculture, fishing, motor vehicles, ships, submarines, bicycles, and other portable power systems in the future. This paper emphasizes the production of lightweight bipolar plates to solve several existing problems in the PEMFC system, including weight, cost, and integration. Conventional bipolar plates account for approximately 90% of the weight of battery packs. Therefore, an injection molded flow-field plate constructed from polymethylmethacrylate (PMMA) is developed herein to reduce the weight of the PEMFC system. Computer-aided engineering (CAE) mold flow analysis is then used to simulate the experimental design based on the finished products. Experimental analysis is also performed on the adhesion results of the plates. The results indicate that the establishment of the injection mold using CAE simulation improves mold development and reduces cost. Mechanical coarsening on the surface of the PMMA results in improved adhesion (> 50 N) at temperatures higher than 80 °C. Thus, mechanical coarsening is suitable for the PEMFC system. The problem of conventional weight is solved by reducing the weight by 70%.

A High Conductive Composite Bipolar Plate with Conductive Network Constructed by Chemical Vapor Deposition

“…Metal BPs have a higher mechanical strength, good air permeability, electrical conductivity, and are easier to process than graphite BPs; however, in order to prevent metal BPs from corroding in the operating environment of a PEMFC, a more expensive surface treatment and modification is required [10,11]. Resin/graphite composite BPs have many advantages such as their light weight, easy Energies 2022, 15, 4979 2 of 16 fabricability, corrosion resistance, inexpensiveness, etc., but their electrical conductivity and contact resistance are lower than graphite BPs [12][13][14]. Recently, the composite BPs have aroused extensive research interest because of their higher corrosion resistance and easier fabricability.…”

Post transition metal substituted Keggin-type POMs as thin film chemiresistive sensors for H2O and CO2 detection

“…POMs were synthesised in acetonitrile via base degradation of Na 3 PW 12 O 40 with methanolic TBA(OH) to yield the lacunary species, followed by a substitution reaction with the appropriate post-TM salt as outlined in the (ESI †). [17][18][19][20][21] Simple chemiresistive devices were fabricated with two interdigitated indium tin oxide (ITO) coated electrodes bridged by the sensing material (Fig. S1, ESI †).…”
