What is a fuel cell In today’s society, experts are continuously searching for new forms of renewable energy to minimize greenhouse gas emissions (GHGs). Among the many different causes for climate change in Canada, transportation is one of the leading sources, from individual locomotion to the shipping of goods1. However, experts believe that the emergence and budding popularity of electric vehicles in the recent years can greatly reduce the emission of these GHGs. Among the variety of electric vehicles, hydrogen fuel cell vehicles are becoming a viable option. Hydrogen fuel cells use hydrogen and oxygen as fuel to produce electricity, heat and water . Hydrogen fuel cells are intriguing as it requires the simplest and most abundant element on earth, hydrogen. 2 Hydrogen Fuel Cell Structure and Chemistry Rather than utilizing the typical process of reforming to obtain hydrogens from hydrocarbons, hydrogen is instead obtained from water through electrolysis. Electrolysis is a process that induces chemical change by the passage of an electrical current through a solution.3 Fig 1: Schematic showing the basic workings of a Hydrogen fuel cell and the chemistry involved.Source: https://en.wikipedia.org/wiki/File:Fuel_Cell_Block_Diagram.png 4 All fuel cells are made of four major components: the anode, electrolyte, cathode and catalyst. Hydrogen, the fuel, interacts with the anode which consists of a catalyst, typically platinum. The platinum oxidizes hydrogen and splits protons and electrons from the fuel. Thereafter, the electron moves to the cathode via an external source which is often a wire, causing an electrical current to occur. Meanwhile, the protons migrate to the cathode through the electrolyte, which for instance can be potassium hydroxide. Additionally, the electrolyte is specifically used for the migration of positive hydrogen ions, moreover, the type of substance utilized here will determine the type of fuel cell produc>GET ANSWER Let’s block ads!
