Polymer Electrolyte Membrane (PEM) Fuel Cells (PEFC) | Proton Exchange Membrane (PEM) Fuel Cells

Polymer electrolyte membrane (PEM) fuel cells—also called proton exchange membrane fuel cells—deliver high-power density and offer the advantages of low weight and volume, compared with other fuel cells. PEM fuel cells use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum catalyst. They need only hydrogen, oxygen from the air, and water to operate and do

Quantum Tunnelling Composite (QTC) | A Pressure Switching And Sensing Material Technology | Electro Mechanics Components

     QTC is a composite made from micron-sized metallic filler particles (Silicone Rubber) mixed into an elastomeric matrix. Quantum tunnelling composite is a flexible polymer that exhibits extraordinary electrical properties. In its normal state it is a perfect insulator, but when compressed it becomes a more or less perfect conductor and able to pass very high currents. History: First produced

Carbon Fibre Reinforced Plastics | Carbon Fibre Reinforced Polymers Use | CFRP Applications

      The Composite’s properties are mainly influenced by the choice of fibers. Three types of fibres are Glass fibre, Carbon fibre, Aramid fibre. All fibres have generally higher stress capacity than ordinary steel and are linear elastic until failure. The most important properties that differ between the fibre types are stiffness and tensile strain. Carbon Fibre Properties: High Modulus of

Graphene | Graphene Technology | Graphene The Material Of The Future | Graphene Review | Graphene Properties | Graphene Production

       The graphene is a substance which has a single-layer crystal lattice of carbon atoms, which is unusual since it is different from all of the materials of its kind. Several researchers have identified a way of making this substance, which allows them to use it in various fields and especially for the high-speed electronic devices. Graphene Definition: Graphene is

Jetpack | Personal Flying Jetpack Machine | Jetpack Machines

        This Jetpack consists of a built-in gasoline engine driving twin ducted fans which produce sufficient thrust to lift the aircraft and a pilot in vertical takeoff and landing, enabling sustained flight. Jetpack Development: Since the beginning of time man has dreamed of personal flight – the ability to fly as free as birds and escape gravity’s pull. From the

Artificial Photosynthesis | Artificial Photosynthesis To Create Clean Fuel | Artificial Photosynthesis Solar To Fuel | Artificial Photosynthesis Process

Artificial photosynthesis is one of the newer ways researchers are exploring to capture the energy of sunlight reaching earth.      Photosynthesis: Photosynthesis is the conversion of sunlight, carbon dioxide, and water into usable fuel and it is typically discussed in relation to plants where the fuel is carbohydrates, proteins, and fats. Using only 3 percent of the sunlight that reaches
