Phosphoric acid fuel cell
Download as PPTX, PDF4 likes3,487 views
A phosphoric acid fuel cell has two porous electrodes that collect charge - a negative electrode of hydrogen gas and a positive electrode of oxygen or air. Phosphoric acid acts as the electrolyte, and platinum catalysts on both electrodes accelerate the electrochemical reactions. Hydrogen ions migrate through the electrolyte to the positive electrode, where they interact with oxygen to produce water, while electrons flow through an external load to provide electricity. The fuel cell operates between 150-200 degrees Celsius and has an actual voltage of 0.7-0.8 volts, lower than its theoretical potential of 1.23 volts.

This document provides an overview of fuel cells, including their basic components and operation. It discusses how fuel cells work by separating hydrogen ions and electrons at the anode, with the electrons powering an external circuit before recombining with oxygen and ions at the cathode to form water. Two types of fuel cells are then described in more detail: phosphoric acid fuel cells, which were the first commercialized and use liquid phosphoric acid as the electrolyte, and alkaline fuel cells, which use an aqueous potassium hydroxide solution and react hydrogen and oxygen to produce water, heat and electricity.Fuel cell

The document discusses hydrogen production and a potential hydrogen economy. It outlines that hydrogen is mainly used today in the Haber process for ammonia production and hydrocracking of petroleum. The hydrogen economy proposes using hydrogen as an energy carrier produced from water using energy rather than being an energy source itself. The main challenges to a hydrogen economy are high costs, developing efficient hydrogen storage methods, and building the necessary infrastructure including production, transportation and distribution. Current hydrogen is mainly produced via natural gas reforming, but other methods discussed are electrolysis, gasification, and biological and photolytic production.Fuel cell ,PEM Fuel Cell

An electrolytic cell uses electrical energy to drive non-spontaneous redox reactions by pushing electrons from the anode to the cathode. In electrolytic cells, oxidation occurs at the anode and reduction occurs at the cathode, unlike voltaic cells where the reactions are spontaneous. A common example is the electrolysis of water, where applying a current splits water into hydrogen gas at the cathode and oxygen gas at the anode. Electrolysis can also be used to produce chlorine from molten sodium chloride or to electroplate metals onto objects by reducing metal ions at the cathode.Electrolysis chemist

Electrolysis is the process of using electricity to cause a non-spontaneous chemical reaction. During electrolysis, ions migrate towards the electrodes and undergo oxidation or reduction reactions. At the cathode, positively charged ions are reduced and neutral atoms are formed. At the anode, negatively charged ions are oxidized and neutral atoms or molecules are formed. The products of electrolysis depend on factors like the ions present in the electrolyte, their concentration and position in the reactivity series, and the nature of the electrodes. Electrolysis has applications in purifying and extracting metals, and in electroplating.22CYT12-Unit_I_Electrochemistry - EMF Series & its Applications.ppt

Electrode potential is a measure of the tendency of an electrode to gain or lose electrons in a half-cell reaction. Standard electrode potentials (E°) are measured under standard conditions. E° values are used to determine the feasibility of redox reactions, calculate free energy change, and understand the oxidizing or reducing properties of substances. The electrochemical series arranges E° values from strongest reducing agent to strongest oxidizing agent. E° data can also be used to calculate non-standard electrode potentials and cell potentials using Nernst equations.2-Electrochemistry.pptx

This document discusses voltaic cells and the potential differences between half-cells. It explains that connecting two half-cells with different electrode potentials through an external circuit and salt bridge allows electrons to flow spontaneously from the negative half-cell to the positive half-cell. Specifically, it gives the example of a Zn/Cu voltaic cell, where the Zn half-cell acts as the anode undergoing oxidation and the Cu half-cell acts as the cathode undergoing reduction. When connected, the potential difference between the half-cells can be measured as 1.10 volts using a high resistance voltmeter.apchapt17.ppt

This document provides information on oxidation-reduction (redox) reactions and electrochemistry:
[1] Redox reactions involve the transfer of electrons between oxidizing and reducing agents. Common examples are corrosion reactions.
[2] Galvanic (voltaic) cells generate electricity through spontaneous redox reactions. The anode is where oxidation occurs and electrons are released. The cathode is where reduction occurs and electrons are gained.
[3] Cell potential depends on the relative tendencies of substances to be oxidized or reduced, as measured by standard reduction potentials. More negative potentials indicate greater reducing ability; more positive potentials indicate greater oxidizing ability.Option C Nernst Equation, Voltaic Cell and Concentration Cell
