Fuel cells are a form of renewable source of energy. It mainly involves usage of hydrogen and oxygen which together combine to form water and energy. The main advantage of using this is that it does not produce carbon dioxide as an end product. Carbon dioxide is found to be one of the major sources of greenhouse effect. Thus this method is ideal for energy production but the major drawback is its cost. It utilizes highly expensive Pt catalyst making it not suitable for cost efficient energy production method.
In a fuel cell, hydrogen forms the anode and oxygen from the atmospheric air forms the cathode and platinum is chosen as a catalyst. The membrane is made of nafion. At the anode, electrons are separated from the protons by the catalyst. The protons travel through the membrane and reach the anode where it combines with oxygen to form water, which is the byproduct of this process. The electrons travel in an external circuit which creates the electrical energy.
Proton Exchange Membrane Fuel Cells (PEMFCs) are a type of renewable energy source which function by converting hydrogen produced from renewable sources such as biomass into water and clean combined heat and electric power, since carbon dioxide is not generated as a bi-product. The method of energy production can create energy efficiently at 62%, but one of the main problems is their expensive cost. A PEM Fuel Cell functions by the reaction of pure hydrogen and oxygen gases into water and usable energy (2H_2+ O_2=2H_2 O+energy). The hydrogen adsorbs onto the surface of the Platinum electrode, freeing the electron and breaking the hydrogen bond. Graphene Oxide could function as the membrane electrode assembly in a PEMFC. With a high ionic conductivity, Graphene Oxide could potentially take the place of the Pt catalyst as the main membrane used in PEMFCs. Hence graphene oxide is found to be more effective than nafion membrane.
The conclusions from these research yield high accuracy Horsepower results; however, more importantly for this research assignment, all of the data collected, experiments created, and information obtained were done in a hands on, active learning environment. This type of applied learning comes with many benefits in comparison to traditional learning in a classroom setting. One of the main benefits is that the student can immediately learn by doing and see the impact of a scientific or engineering theory on a subject in a real-world application. Furthermore, the experiments were designed to give the students a sense of what it would be like to work as a professional and prepare them for post-graduation. Giving the students such hands-on experience proved to be invaluable because this type of applied learning is very similar to how the industry operates on a daily basis.
