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 ...

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 ...

Gas Analysers for Fuel Cell Research
Electrochemical fuel cells are envisaged as a potential successor technology to combustion engines in the automotive sector. Although studies have considered numerous gaseous elements as the fuel source for electrochemical stacks, hydrogen (H2) remains the primary element of interest in automotive engineering. Gas analysers have proven instrumental in demonstrating the advantages and drawbacks of ...

Designing a sustainable hydrogen energy economy
A general vision of a sustainable energy economy relying substantially on hydrogen produced from renewables is sketched as a potential solution to the twin global crises of climate change and depleting oil reserves. Core differences between this 'sustainable hydrogen economy' (SHE) and the original hydrogen economy (HE) proposed in the early 1970s are discussed. In transport, rather than posing a ...

Oscillating syngas production on NiO/YSZ catalyst from methane oxidation
Introduction Nickel oxide/yttrium-stabilized zirconia (NiO/YSZ) is a state-of-the-art anode used in solid oxide fuel cells (SOFCs). Despite its excellent electrochemical activity in hydrogen fuel cells, there are barriers to the storage of hydrogen, which have stimulated interest in the investigation of chemical reactions on NiO/YSZ involving methane, a major component of natural gas. Many ...

Sustainable development with renewable energy resources: a review
The most visible effects of the sustainable development movement are found in several global issues such as the greenhouse effect, stratospheric ozone depletion, and loss of biodiversity. Combustion of fossil fuels and global warming are closely associated with each other. There is an urgent need to replace fossil fuels to renewable energy sources. Renewable energy is one of the few means by ...

Why is Humidity / Moisture Control Important in a Fuel Cell?
The root of all of this is that Nafion membranes must stay hydrated to function properly. If they are not fully humidified the conductivity decreases and therefore more of the electricity is converted directly to heat before it leaves the membrane (I2R heating). If it gets too dry it basically stops functioning as a proton transporter. All of this sounds great since a Hydrogen Fuel Cell consumes ...

SnO 2 -Nafion ® nanocomposite polymer electrolytes for fuel cell applications
Fuel cells are capable to exploit the combustion of hydrogen to convert chemical energy into electricity. Polymer electrolyte fuel cells based on Nafion membranes are able to work in a relatively low temperature range (70–90ºC) but require operating relative humidity (RH) close to 100%. To develop proton-exchange membranes with adequate performances at low RH, an attractive strategy ...

Solar powered solid oxide fuel cell with thermoelectric generator
Durable, location independent, environmental–friendly sources of energy which allow for modular, few moving parts, low operating noise, high electricity generation efficiency and compact technology are highly desirable. Solid oxide fuel cells (SOFCs) are promising for such energy system development, since they are energy efficient and, if pure hydrogen is used, have virtually no emissions of ...

Model of a non-isothermal tubular ammonia reformer for fuel cell applications
There is an increasing interest in the use of ammonia as hydrogen carrier for fuel cell applications. Ammonia decomposes catalytically into hydrogen and nitrogen without the emission of catalyst poisoning or polluting gases such as CO. Ammonia decomposition in a catalytic reformer which comprises of a Ni based wall reactor is modelled and calibrated using actual experimental data in order to ...

Hydrogen plays a key role in the European Green Deal
European Commission President Ursula von der Leyen launched the European Green Deal last Wednesday, on 11 December. The goal is ambitious. If the European Green Deal becomes reality, the European Union will become climate neutral by 2050. To reach the goal, the EU will have to overturn almost every policy area. Europe inevitably needs hydrogen to reach this arduous goal. Looking at the ...
