Exergetic analysis of fuel cell micropowerplants fed by methanol

Platinum supported on resorcinol–formaldehyde based carbon aerogels for PEMFC electrodes: Influence of the carbon support on electrocatalytic properties

“…The hydrogen/air-fed polymer electrolyte membrane fuel cell (PEMFC) is an attractive power source because of its high power density [1], high efficiency [2] and cleanliness. The continual improvement of its performance during the past decades [3] is a chance to turn to a cleaner automotive society [4,5].…”

Influence of the microchannel plates design on the efficiency of the methanol steam reforming in microreactors

“…2) shows that catalyst CuO/ZnO displays the low reduction temperatures with a narrow peak at 219 • C, thus indicating existence of small CuO particles and hence, a high Cu dispersion after the reduction. According to a correlation between the temperature of the reduction and the copper crystallite size for the Cu/ZnO catalysts [12], the mean size of the copper crystallites in our catalysts can be estimated as 8.5-10.0 nm. The BET surface area of the CuO/ZnO measured by the nitrogen adsorption was 39 m 2 /g.…”

Exergy and Energy Analysis of Solid Oxide Fuel Cell Fuelled Using Methanol Propane, and Butane

“…The chemical Exergy according to [25] is the total amount of work, which can be acquired from a stream of material brought from the environment (restricted dead) state to the total dead (unrestricted) state while exchanging only materials and heat with the environment. The equation for the chemical and thermal Exergy is specified by [21,24,26] …”

“…[ [20][21][22] analyse various integrated system based on Exergy destruction calculation and second law efficiencies. They also show different ways achieved detailed physical and chemical Exergy calculations for both SOFC and PEMFC system.…”
