Propane Fuel Cell Reaction

With only one step a fuel cell directly converts fuel into usable electricity and heat through a chemical reaction.

Propane fuel cell reaction.

Uses for the products of the reaction. The mcfc has the most complex fuel cell reaction of all the cells available commercially. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen usually from air to sustain the chemical reaction whereas in a battery the chemical energy usually comes. Fuel cells are characterized by their electrolyte material.

Propane is used for patio heaters hot tub heaters furnaces ect. In this work two of the four propane fuel cell reactions propane dehydrogenation and water dissociation were examined using nickel alloy catalysts. The emissions are water carbon dioxide with the result being higher efficiency minimal noise and safer emissions. The ultimate products of this reaction are carbon dioxide and hydrogen.

Like methane propane can be steam reformed albeit at milder temperatures. The methane smr reaction takes place at temperatures of 750 c to 950 c but propane can be reformed to hydrogen at 200 c to 350 c. 6 2 the mcfc principle. For example nonprecious metal catalysts can replace platinum.

Density functional theory dft was used to determine propane adsorption energies desorption energies and transition state energies for both dehydrogenation and hydroxylation reactions on a ni 100. Please visit our sunfire solid oxide fuel cells page for information on these propane natural gas fuel cells. The reaction drives a current and releases protons that then interact with oxygen at the cathode to produce water. Its low boiling point 42 c makes propane popular for barbeques and portable stoves.

The electrolyte is a mixture of alkali metal carbonates typically 62 lithium carbonate and 38 potassium carbonate by molecular proportions a eutectic 1 which melts at 550 c which is heated to between 600 c and 1000 c and in its molten state. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel often hydrogen and an oxidizing agent often oxygen into electricity through a pair of redox reactions. Paul breeze in fuel cells 2017. Atrex solid oxide fuel cells have been discontinued and are no longer available for sale.

The use of propane fuel in high temperature 120 c polymer electrolyte membrane pem fuel cells that do not require a platinum group metal catalyst is being investigated in our laboratory. Advantages of this class of fuel cells include high combined heat and power efficiency long term stability fuel flexibility low emissions and. Propane is used as fuel in furnaces for heat in cooking as a energy source for water heaters laundry dryers barbecues and portable stoves. High temperature polymer electrode membrane fuel cells that use hydrocarbon as the fuel have many theoretical advantages over those that use hydrogen.
