The polymer electrolyte membrane fuel cell (PEMFC) also known as proton exchange membrane fuel cell, polymer electrolyte fuel cell (PEFC) and solid polymer fuel cell (SPFC) was first developed by General Electric in the USA in the ’s for Cited by: This book focuses on the materials used for fuel cells, solar panels, and storage devices, such as rechargeable batteries.

Fuel cell devices, such as direct methanol fuel cells, direct ethanol fuel cells, direct urea fuel cells, as well as biological fuel cells and the electrolytes, membranes, and catalysts used there are detailed. 20 Fuel cell systems / edited by Leo J.M.J.

Download Citation | Fuel Cells | During the past decade, fuel cells have received an enormous amount of attention all over the world as novel electrical energy conversion systems. The fuel cell stack from combined assembling cells is the most important part of a fuel-cell power system, like an engine in the conventional vehicle.

The FC stack provides the current required by governing of a fuel flow rate through the anode channels, that is, the fuel flow rate varies according to the system power requirements [ 5 ].Cited by: 1.

From Fig. alone one would conclude that there is great theoretical efficiency potential for direct carbon fuel cell (DCFC), polymer electrolyte fuel cell (PEFC), direct oxidation of methane, and intermediate temperature SOFC.

One would also conclude that ammonia and methanol are better than hydrogen. High efficiency is very desirable, but real fuel cells have irreversibilities. He has worked on fuel cell technology sinceworking in the areas of hydrogen production and PEM fuel cell stack components. He has been awarded 12 U.S.

patents, authored over 40 papers related to fuel cell technology, and presented over 50 oral papers at national by: Technical Data Book-Petroleum Re-Ž. fining w x 11 A Hamnett, A liquid-feed solid polymer electrolyte direct methanol fuel cell operat-Ž.

As one of the most efficient pathways to provide clean energy, fuel cells have attracted great attention in both academic and industrial communities. Proton exchange membranes (PEMs) or proton-conducting electrolytes are the key components in fuel cell devices, which require the characteristics of high proton conductivity as well as high mechanical, chemical and thermal Author: Liang Zhai, Haolong Li.

The ideal fuel for a fuel cell power plant for electric vehicles is methanol. This fuel is reformed to hydrogen, which combines with oxygen from the air in an acid electrolyte (phosphoric, more» solid polymer, or superacid) fuel cell to produce electricity. Demonstration projects regarding the development of fuel cell hybrid electric vehicles (FCHEVs) and in particular minibus, citycar, bicycle, tractor and tractor projects intends to demonstrate that the fuel cell can be applied in the farm context because hydrogen could be produced on site using different methods (biomass, wind Cited by: 3.

Proper water management is critical for near-ambient temperature operation of a fuel cell. A simplified water balance model has been developed to predict when incipient flooding/dehydration may take place.

The present model is based on multicomponent diffusion in the electrodes and molar balance in the flow by: 2. Density functional theory was used to design a non-noble metal catalyst for low temperature oxygen reduction. A core–shell catalyst of Ag|AgxCu5-xZn8 was found to have an electronic structure predicted to be near optimal for weak oxygen bonding, and the activation energy for dissociation was low.

This catalyst was made via evaporation and sputtering and tested as the Cited by: 4. The direct methanol fuel cell (DMFC) is a promising power source for micro- and various portable electronic devices (mobile phones, PDAs, laptops, and multimedia equipment) with the advantages of easy fuel storage, no need for humidification, and simple by: 6.

As a clean energy source, hydrogen gas (H 2) has potential if used in an electricity generating fuel cell (Caglar, ). H 2 production by reforming of HC-based fuels in suitable fuel processors has become more and more important, in particular for both mobile and residential fuel cells applications (Specchia et al., ).

Disclosed is a metal-air fuel cell based on a solid oxide electrolyte.

A self-supported direct borohydride-hydrogen peroxide fuel cell system with internal manifolds and an auxiliary control unit is reported.

The system, while operating under ambient conditions, delivers a peak power of 40 W with about 2 W to run the auxiliary control unit. A critical cause and effect analysis, on the data for single cells and stack, suggests the optimum concentrations of Cited by: Transport of water in a fuel cell system between a first gaseous stream having a higher concentration of water and a second gaseous stream having a lower concentration of water, by mass and heat transfer, is effected through a plurality of non-hydrophilic membranes in a membrane module, such that water uptake of the selective layer is less than 10 wt % Cited by:   A star‐shaped porphyrin‐based molecule with four perylene bisimide arms (PBI‐Por) was designed as a non‐fullerene electron acceptor for application in solar cells.

In their Communication on page ff., Z. Wang, W. Li, and co‐workers show that the combination of a donor polymer with PBI‐Por in a solar cell results in a photoresponse from λ= to nm. Polymer membranes allow ionic liquids to be prepared as solid electrolyte films for their application as separators in fuel cell devices.

When ionic liquids are mixed with common polymers, which act as a plasticizer, their transport properties can be enhanced due to the increase of the ion dissociation and local dynamics in their structure [4].

Figure 2: Modulus data from glass-ceramic solid oxide fuel cell seal material at elevated temperatures. The results are from the same material heat treated at ºC for different durations.

This causes a reduction in the modulus of the hour treated sample at. The analysis of above plot LiAlH 4 (LAH) shows that the gravimetric weight ratio of hydrogen is wt%; thereby LAH seems a potential hydrogen storage medium for future fuel cell powered vehicles.

But, in practice the hydrogen storage capacity is reduced to wt% due to the formation of LiH + Al species as the final by: The molten carbonate electrolysis cell (MCEC) provides the opportunity for producing fuel gases, e.g., hydrogen or syngas, in an environmentally friendly way, especially when in combination with renewable electricity resources such as solar, wind, and/or hydropower.

The CO 2 concentration difference between ambient air and exhaust gases created by combusting fossil fuels is an untapped energy source for producing electricity.
