Energy from the ground that has limited supplies, either in the form of gas, liquid or solid, are called non renewable resources. They cannot be replenished, or made again, in a short period of time. Examples include: oil (petroleum), natural gas, coal and uranium (nuclear). Oil, natural gas and coal are called “fossil fuels” because they have been formed from the organic remains of prehistoric plants and animals . In present scenario the hole world is tollay dependable on these types of energy. But the problem is that these types of energy sources continuously decreasing .Therefore a huge shortage in energy bank. Thats why we have to find some new energy source which is renewable source of energy and also environment friendly. Fuel cell is a source of energy. Where we use hydrogen and oxygen as a fuel. Basically the pressure of hydrogen is constant, only flow of oxygen pressure is varied. Our aim is that what will happen if we varies oxygen pressure and the corresponding change on load voltage . here we also design filter for better output.
