摘　　要：Proton-exchange-membrane fuel cells(PEMFCs)have the characteristics of zero emissions,a low operating temperature and high power density,and have great potential in improving energy-utilization efficiency.However,fuel cells are still quite expensive as a result of the cost of key components,including the membranes,catalysts and bipolar plates of PEMFCs.As a result of the cost and importance of these items,most researchers have focused on improving the lifetime and performance of fuel-cell stacks in recent years.In contrast,seals,sealants and adhesives play a more mundane role in the overall performance of a fuel cell,but failure of these materials can lead to reduced system efficiency,system failure and even safety issues.Little attention has been paid to the performance and durability of these products but as other fuel-cell components improve,these seals are becoming an even more critical link in the long-term performance of fuel cells.This article highlights the importance and background of fuel-cell seals.The latest research progress on the mechanical properties and structural optimization of different sealing materials is reviewed.
