Hydrogen energy, as a kind of efficient and clean energy, can simultaneously alleviate the energy crisis and reduce environmental pollution and has become the focus of global renewable energy development. Hydrogen-powered polymer electrolyte membrane fuel cells (PEMFCs) with the advantages of high chemical to electrical energy conversion efficiency, low operating temperature, and near-zero pollution have been widely researched and developed to be the most suitable power source for electric vehicles (EV), aviation, residential backup power, as well as energy storage applications up to grid-scale.An intrinsic issue of hydrogen polymer electrolyte fuel cells (PEFCs) where the inlet gas pressure difference between anode and cathode causes damage to the membrane during caustic operation conditions, especially when they are used for aircraft or submarines. A precautionary method has never been applied to eliminate this phenomenon. Novel membranes with higher mechanical and chemical strength can solve this issue. New PEM membranes will be developed to increase such properties to against any damage caused by pressure attack, load or vibration etc. because of caustic operation conditions. It will also allow pressurised fuel supply which improves mass transfer and overall energy output.Hydrogen-sensitive coating will be applied on the surface of cathode flow field channels and pressure monitoring electronics will be embedded on the membrane, gas diffusion layer (GDL) and for in-situ pressure, leakage and humidity monitoring, avoiding the need for bulky and expensive externally connected to control and management systems.

作为一种有效而清洁的能源，氢能可以同时减轻能源危机并减少环境污染，并已成为全球可再生能源发展的重点。 Hydrogen-powered polymer electrolyte membrane fuel cells (PEMFCs) with the advantages of high chemical to electrical energy conversion efficiency, low operating temperature, and near-zero pollution have been widely researched and developed to be the most suitable power source for electric vehicles (EV), aviation, residential backup power, as well as energy storage applications up to grid-scale.An intrinsic issue of hydrogen polymer electrolyte fuel cells （PEFC）在碱性操作条件下阳极和阴极之间的进气气压差会损害膜，尤其是当它们用于飞机或潜艇时。从未应用一种预防方法来消除这种现象。具有较高机械强度和化学强度的新型膜可以解决此问题。由于苛刻的操作条件，将开发出新的PEM膜，以将这种特性提高到由压力攻击，负载或振动等造成的任何损害。它还将允许加压燃料供应，以改善质量转移和整体能量输出。氢敏感的涂层将应用于电极流动场通道的表面，并将压力监控电子设备嵌入膜，气体扩散层（GDL）（GDL）（GDL），以及对静脉压力，漏水和湿度，渗漏和湿度监控，避免使用稳定的型号和昂贵的外部系统，以控制和稳定的型号，以适应型号和稳定的系统。
