An emerging approach for strategy evaluation in fuel cell development
This is the first research paper on the topic of Taiwan fuel cell development to combine the two theoretical (AHP and FMCDM) approaches. The conclusion suggests that the priority for Taiwan to develop fuel cells are the fields of 3C electronics, power generation equipment, motorcycles and automobiles. The difficulties the industry has encountered and faced, in turn, are the technology ...

Development of a generic fuel cell model: application to a fuel cell vehicle simulation
In this paper, a novel approach to fuel cell modelling is proposed. The model is obtained from manufacturer datasheets and is able to represent the behaviour of any hydrogen fuel cells. The simulation results are as expected with an error in the range of ±1%, provided a controlled stack internal humidity. The procedure to extract data from fuel cells datasheet is described along with the method ...

Strategic innovation in sustainable technology: the case of fuel cells for vehicles
This paper explores the gap between the implied theoretical 'assumption' that development of technologies for sustainable development should be a smooth evolutionary transition and the reality of such change. Here, we identify a split between macro, long-term models of transition to greater environmental sustainability through innovation, as found in theories of ecological modernisation, ...

Characterisation of two-phase flow and its impact on the performance of a Polymer Electrolyte Membrane fuel cell stack
Water management is one of the most critical issues for high-performance Polymer Electrolyte Membrane (PEM) fuel cells. A flow network model was developed to study the possibility of two-phase flow inception along the gas flow channels in the cathode side of a PEM fuel cell stack. The conventional Darcy-Weisbach equation and homogeneous flow model are used to estimate the pressure distributions ...

Conception and optimization of a membrane electrode assembly microbial fuel cell (MEA-MFC) for treatment of domestic wastewater
A membrane electrode assembly (MEA) for microbial fuel cells (MEA-MFC) was developed for continuous electricity production while treating domestic wastewater concurrently. It was optimized via three upgraded versions (noted α, β and γ) in terms of design (current collectors, hydrophilic separator nature) and operating conditions (hydraulic retention time, external resistance, aeration rate, ...

Mathematical model of a PEM fuel cell incorporating CO poisoning and O2 (air) bleeding
A one-dimensional mathematical model has been developed for a fully hydrated and isothermal PEM fuel cell. Mass transport in the gas flow channels, electrode backing and catalyst layers is accounted for, along with the adsorption, desorption and electro-oxidation of hydrogen and carbon monoxide. Additionally, the heterogeneous catalysis of hydrogen and carbon monoxide with oxygen is included for ...

Enhanced power production from microbial fuel cells with high cell density culture
Improvement of power production in a microbial fuel cell (MFC) with a high cell density culture strategy was developed. By using high cell density culture, the voltage output and power density output of the MFC were enhanced about 0.6 and 1.6 times compared to the control, respectively. Further analysis showed that riboflavin concentration in the MFC was dramatically increased from 0.1 mg/L ...

Analysis of availability and accessibility of hydrogen production: An approach to a sustainable energy system using methane hydrate resources
It is considered that use of hydrogen as an energy source may contribute to environmental improvement and provide an alternative energy system. Moreover, it is anticipated that hydrogen will be in great demand in the near future for use in such vehicles as fuel cell-based cars. Research and development of a number of advanced methods of hydrogen production (OTEC, water photolysis using a ...

Who uses innovative energy technologies, when and why? The case of fuel cell MicroCHP in households
Users can play an important role in the diffusion of sustainable energy technologies. Using a postal survey and focus group discussions, the paper explores the characteristics, motives and expectations of household users in the case of fuel cell?driven small combined heat and power plants. (Potential) users are highly educated and well off, almost exclusively male and relatively old. Their main ...

Fuel Cell Voltage Monitoring Considerations
Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There are a few ...

Where does CO2 free hydrogen gas come from?
It’s no longer a question whether hydrogen will have a major impact on the automotive industry, but rather an accepted fact that it will. Volvo’s and Daimler’s recent announcement (read here) of joint efforts in developing and manufacturing fuel cells is the latest sign of the importance of hydrogen for energy storage. But how is hydrogen produced, where does the gas come from, ...

Simultaneous carbon and nitrogen removal using a litre-scale upflow microbial fuel cell
A 10 L upflow microbial fuel cell (UMFC) was constructed for simultaneous carbon and nitrogen removal. During the 6-month operation, the UMFC constantly removed carbon and nitrogen, and then generated electricity with synthetic wastewater as substrate. At 5.0 mg L−1 dissolved oxygen, 100 Ω external resistance, and pH 6.5, the maximum power density (Pmax) and nitrification rate for ...

Coming In Out of the Cold: Hybrids Put to the Test
Untitled Document Point Roberts, WA, Delta B.C.- May 25, 2004 With gas prices reaching an all time high and not much promise of an end in sight, hybrid technology is falling under the lens of some careful scrutiny these days with investors. In a recent article in MIT’s Technology Review, author Peter Fairley estimates “though buyers would have to pay more ...

South Africa`s fuel cell plan risks failure without support
An ambitious strategy to create fuel cell products for export will need incentives and cross-government backing to bear fruit, says Radhika Perrot. South Africa's Department of Science & Technology (DST) has been laboriously pushing for the development of hydrogen fuel-cell technology through an ambitious research and development (R&D) strategy since 2005. Fuel cells can convert the ...
