6 Abstract This is a summary of the research experiment on hydrogen fuel cell. The focuses on the chemical activities and the reaction processes that occur during chemical changing process to electricity. Mechanism mainly based on simple combustion. Simple fuel cells have small area of contact between the electrolyte, electrode plate and gas fuel. Studies have been conducted to solve various problems some of which are in the engineering. The technology of a fuel cell machine is used to generally generate an electrical current that can be directed outside the cell to perform work is also discussed. Though there are different kinds of fuel cells, this paper focuses on hydrogen cells. Chemical reaction mechanisms that generate this current are crucial to how a fuel cell works. This is the reason for the study in order to find the best source of electricity in the world.

7 INTRODUCTION Fuel cell basics Basically, a fuel cell is a device that employs hydrogen as fuel to produce electrons, protons, heat and water. The mechanism technology of a fuel cell is mainly based on a simple combustion reaction as shown below: 2H 2 (g) + O 2 (g) –2H 2 O (l) The electrons can be harnessed to generate electricity in a consumable form via a simple circuit with a load. Simple fuel cells have a very small area of contact between the electrolyte, the electrode plate and gas fuel. Every fuel cell has two electrodes, one positive and one negative called respectively, an anode electrode and cathode electrode. The reaction mechanism, as shown above, is the one that produces electricity at the electrodes (Thanh et al. pg. 984). Hydrogen is the basic fuel, but fuel cells also need oxygen. One significant appeal of fuel cells is that they provide electricity with very little pollution. Much of the gas proportions that is oxygen and hydrogen are actively used in generating current and ultimately they combine to form a harmless byproduct, namely water. One detail of terminology: a single given fuel cell provides a tiny amount of direct current termed as DC (direct current electricity). Practically, numerous fuel cells are normally assembled into a stack ( Ajay, et al. pg. 31) Cell or stack, the principles are similar. Why are we studying fuel cells? For our current time, there is a lot of active study throughout the globe on solving engineering problems that currently prevent fuel cells from becoming commercially accessible.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
