Fuel Cell Essay

One of the important issues to ensure the safety of a ship in the case of a gas leak is the condition of air flow inside the fuel cell stack package. Poor air flow increases the risk of fire or explosion by accumulating leaked gas in one place. Against this backdrop, the installation place for a ventilating fan and its capacity should be properly decided to make the air flow smooth inside the package, and an alarm unit and gas detector should be installed at the proper place to detect gas leak. In

Name: Institution: Course: Instructor: Date: The Conversion of Solar (PV) Energy into Hydrogen Gas for Fuel Cells. Introduction Solar photovoltaic (PV) systems convert sunlight into direct current. For this to be achieved, semi-conducting materials would be required to induce the photovoltaic effect. A photovoltaic system comprises solar panels, each fitted with a number of solar cells that supply solar energy to the system. In the absence of sunlight, solar power would be available for

Introduction- Batteries/Fuel Cells Fuel cells operate via a chemical reaction which generates electricity. All fuel cells contain a positive anode, a negative cathode and an electrolyte to carry the charged particles through the cell. They also contain a catalyst which will increase the rate of the reaction occurring. The electricity produced can then used to power various appliances. This, in turn, creates a circuit with the current continually flowing in and out of the cell until the reaction ceases

Potential of Microbial Fuel Cells A microbial fuel cell (MFC) is a device that converts chemical energy to electrical energy by the catalytic and metabolic reactions of microorganisms. The microorganisms function as a catalyst in the electron transfer between the electrodes. A MFC is just like any other fuel cell in its function which can undergo a half cell reaction. A typical microbial fuel cell consists of anode and cathode compartments separated by a cation (positively charged ion) permitting

Bibliography Cooper, Mary H. “Alternative Fuels” CQ Researcher 15.8 (February 25, 2005): 173-196. Web This source mainly concentrates on the use of hydrogen fuel cells as an alternative to the United States dependency on foreign oil. It elaborates on the negatives of our countries reliance upon external sources for the vast majority of our power production needs, and suggests that hydrogen fuel cells are the answer to a sustainable energy future. The author is a writer for CQ Researcher who concentrates

Hydrogen and Fuel cells Renewable energy Hydrogen and fuel cells are not technically renewable energy although they are everywhere and don't cause much pollution. With hydrogen, it can be used as fuel and the only emission is water. By using hydrogen there can be a large reduction in green house gases and air pollution. Plus the hydrogen can be used in the fuels cells to power electric motors or batteries for electricity. If your wondering what fuel cells is, there pretty much batteries, or what

How fuel cells work A fuel cell is a device that produces an electrical current through a chemical reaction. All fuel cells contain a cathode and an anode, which are positive and negative electrodes, respectively. The chemical reactions which produce electricity occur at the electrodes. Fuel cells also contain an electrolyte, which carries electrically charged particles between the electrodes. A catalyst also aids to speed up the chemical reaction at the electrodes. In fuel cells, an impurity must

Jasmine Nguyen, Annie Vo The energy source that will have a thorough description from how it works to what it’s made of and much more, is hydrogen fuel source. The first fuel cell was invented by Sir William Robert Grove in 1839. Hydrogen is the fuel of destiny mainly due to it’s elevated transformation efficiency, salvaging, and non-contaminating nature. Hydrogen plays a higher role in the sustainability of life and can be employed to cause energy. Hydrogen can also be manufactured using several

already show an increase in landslides, such as the French Alps. Humphry Davy first successfully introduced the concept of a fuel cell in the 19th century. This was followed by by the scientist Christian Friedrich Schönbein, who made work on what were to become fuel cells in 1838. William Grove, a chemist, physicist and lawyer, widely known for basically inventing the fuel cell in 1839. Grove conducted experiments with a gas voltaic battery, proving that electrictricity could be produced from an electrochemical

Alternative Power Solutions Our society has become reliant upon technology and continues to increase with time. Computers and many other electronic devices are used in the houses and educational applications. These technologies depend on the energy companies to function. The quality of power that the consumer receives is determined by the area that they live. There are many different ways that these companies go about providing energy. The largest form of energy in the United States is coal
