Proton exchange membrane fuel cells Essay Example | Topics and Well Written Essays - 5000 words

Proton mass meeting membrane fuel cells - Essay Examplemstance, the teaching of fuel cells helps in reducing dependence on fossil fuels hence reducing the levels of toxic and unwholesome emissions to the atmosphere. However, this form of energy exemplified by proton exchange membrane fuel cells has to compete with reliability, cost and energy talent with established energy sources. The commercialization of the proton exchange membrane fuel cells are closely related to rattling materials considerations including performance, durability and cost. The major setback is to find a combination of materials that will give a effectual outcome on the basis of the above three mentioned factors.The proton exchange membrane fuel cell is in any case referred to as the polymer electrolyte membrane fuel cell. This is so because the name variant depends on the type of electrolyte employed in the model. When the membrane is conveniently hydrated, the fuel cell is referred to as the polymer elec trolyte membrane fuel cell. In this case, there is postgraduate conductivity of protons across the polymeric membrane. Various state of the art proton exchange membrane fuel cells befuddle been developed. Exemplified by thinner membranes of less than 40 micrometers and smaller Pt/C electrodes, some fuel cells puddle been devised for cost reduction. However, these models have demonstrated significantly less operating time of close to 15, 000 hours. This called for the invention of an ion-conductive polymeric membrane as a gas electron barrier. This idea was first coined by William T. Grubb of the General electric automobile Company in 1955. Currently, the most widely employed membrane electrolyte is DuPonts Nafion. This is because it possesses good chemical and mechanistic stability in the challenging proton exchange membrane fuel cell environment.
