  • Fuel Cells And Its Effect On The Environment

    Within the last decade, Fuel Cells have become more advanced and available to buy. The Fuel Cell was originally thought up in 1839, by a man named Sir William Grove, but a working model wasn 't made until 1959. After being used in one of NASA’s space programmes, the research and development on Fuel Cells died down and was put back in storage. In the 1900’s scientists decided to look at new ways to make these products available for commercialization. This has been successful as they are now used for portable generators, off-grid power for telecom stations, and drives for forklifts (FAQ). Fuel Cells being used in more devices and becoming more available to the public is a positive in the world . They are a renewable energy source, which is something the world needs now. A Fuel Cell gets it 's power from the outside, which means it will never run out. They produce energy through a chemical reaction, without the combustion. Every Fuel Cell has a positive end, called the anode, and a negative, called the cathode. The anode and cathode are separated by a electrolyte barrier. Fuel goes to the anode side and oxygen goes to the…

  • Fuel Cell Research Paper

    discussing the beneficial and non-beneficial of fuel cells and associating it with fossil fuels. But first, you might query what fuel cells and fossil is? Well fuel cell is an electrochemical energy stratagem that converts hydrogen fuel as well as oxygen to produce electricity, heat and water. While on the other hand fossil fuel are the products fossils that are really old. For instance the animal and plant fossils but however, the three main sources of fuel are coal, natural gas and…

  • The Effects Of High Organature Proton Exchange Fuel Cells

    High temperature proton exchange membrane fuel cells (HT-PEMFCs) are a promising clean technology, especially for automobile applications.1 These devices generate electricity from the chemical reactions that occur in the anode side of the cell, using H2 as a fuel and generating heat and water as by-products.2, 3 However, experimental studies using HT-PEMFCs show that degradation of the cell can occur after certain hours of operation (around 500 hours).4 Some of the factors that contribute to the…

  • Fuel Cells

    Polarization curve Fuel cell creates 1.16 V of equilibrium potential between hydrogen and oxygen. However, the actual open circuit voltage is around 1 V due to temperature, pressure, and the concentration of the reactant. The ohmic loss is the resistance loss induced by the unique resistances of the component of fuel cell. And the concentration loss occurs when reaction rates of hydrogen and oxygen are faster than their supply rates. (1) The diffusion flux created according to…

  • Compare And Contrast Essay On Electric Vehicles Vs Fuel Cells

    This paper discusses electric vehicles and fuel cells vehicles. Most people use fuel cells vehicles. We tend to think that electric vehicles is better than fuel cells vehicles. In particular, we think that electric vehicles can move using electricity without fuel cells and are environment conscious. Both of them have merits and demerits. I discuss the differences between them. Electric vehicles are propelled by one or more electric motors powered by rechargeable battery packs. They have several…

  • Importance Of Fuel Cell Transport

    Chapter:5 FUEL CELL MASS TRANSPORT Introduction Basic condition to produce or generate electricity from Fuel cell is that, it must have supplied the reactants and removed products to avoid any interruptions So, this process of supplying the reactants and removing the products is known as Fuel cell mass transport process. Mostly in this Chapter we are concerned with the movement of reactants and products within Fuel cell. Various fundamental equations that govern the transport of matter from…

  • Operating Principles In PEM Fuel Cell

    OPERATING PRINIPLE AND LOSSES IN PEM FUEL CELL The polymer membrane is the heart of the PEM fuel cell which has some unique features. It allows protons but it is impermeable to gases, and hence it is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer membrane. A…

  • Japanese Car Culture Essay

    new advancements in economical and eco friendly vehicles (DeFeijter, 2016). The Chinese automobile companies have switched their focus to developing cars that run strictly on batteries, eliminating the need for fuel stations and making the daily commute much more affordable to the average consumer. This makes a quick fix to a quickly developing problem with China’s extreme population growth, not to mention the positive effects it will have on the pollution in their cities as well having immense…

  • Fracking Persuasive Essay

    Fracking is Slowly killing Our Planet and the Solution is Not Out of Reach Sure, fracking can provide a quick and easy process of obtaining fuel, but it is also an quick and easy way of killing our environment. Fracking is a popular practice done around the world; if at high pressure, highly toxic chemicals mixed with water can extract gas from shale. This toxic mixture, at high pressure, is put into a pipe that extends far underground; gas pockets are released and then rise to the top of the…
