Direct Methanol Fuel Cells are considered a notably high promising one amongst energy sources in the renewable energy sector. Its ion or proton-conducting electrolyte is based exclusively on polymer electrolyte membrane fuel cell technology. Fuel cell components and their durability are affected by methanol solution, its concentration, evaporative conditions of water, carbon dioxide evaluation, heat generation, and its sealing components. Non-Destructive Testing is performed on Passive Direct Methanol Fuel Cell components to evaluate their performance and to ascertain their reliability, serviceability, durability, expected life &healthiness. Non-Destructive Testing such as Visual Testing, Liquid Penetrant Testing, Ultrasonic Thickness measurement, hardness measurement, and metallographic examination is used to identify direct or indirect means to find the size and to locate surface and subsurface discontinuities in the materials and components. The materials and components have been examined using Non-Destructive Testing, evaluated, and interpreted for acceptance/rejection or repair and to assure components' safety and reliability.
