“…As presented in this paper, a single air-cooled PEM fuel cell with an open cathode flow field was designed and fabricated using desktop milling [11] and membrane electrode gasket assembly (MEGA) technologies [12]. The influences of the different operational conditions, such as air fan voltage and cell temperature, on the performance of an air-cooled PEM fuel cell were evaluated.…”

“…Pozio et al defined a new technology for the production of a membrane electrode gasket assembly for polymer electrolyte fuel cells. The membrane electrode gasket assembly system was prepared by sealing a previously prepared MEA in a moulded gasket [25]. Convert et al modified electrodes by electrodeposition of cobalt tetraazaanulene complexes as selective oxygen cathodes in a DMFC [26].…”

“…By bonding to all faying surfaces, improved sealing may be possible, although disassembly for repair could be difficult. Pozio, et al (2002) have proposed a membrane electrode gasket assembly (MEGA) technique that encases the membrane in the gasket, eliminating the need for overhanging membrane material, as traditionally required to obtain the necessary sealing function. This design can potentially lower the overall stack cost by reducing the inactive MEA area.…”

Fuel cells have significant potential to improve energy utilization efficiency, but remain quite expensive due to the cost of key components, including the membrane of PEM fuel cells, the catalyst, and the bipolar plates. Due to the cost and significance of these items, extensive research has been devoted to reducing cost and improving the quality and performance of these components. By contrast, seals, sealants, and adhesives play a more mundane role in the overall performance of fuel cells, and yet the failure of these materials can lead to reduced system efficiency, system failure, or even safety concerns. Less attention has been given to the performance and durability of these products, yet as improvements in other fuel cell components are made, these seals are becoming a more critical link in the long term performance of fuel cells. This review paper highlights the importance and background of fuel cell seals; discusses the chemical, thermal, and mechanical environments to which fuel cell seals are subjected; and suggests design and testing protocol improvements that may lead to improved fuel cell system performance.
