Conductivity is a defining property in energy materials, influencing everything from battery efficiency to hydrogen fuel performance. Materials with high ionic conductivity enable faster charge transfer and more stable energy storage. Yet, even slight variations in purity, thermal stability, or environmental conditions can alter performance. To address these challenges, researchers turn to ...
With potential applications ranging from fuel cells to industrial processes, the accurate analysis of hydrogen gas is paramount. ...
In the ever-evolving landscape of energy production, hydrogen fuel cells have emerged as a beacon of promise. These clean and efficient power generators hold the potential to revolutionise our energy infrastructure, ushering in a future where sustainability and performance go hand in hand. However, achieving optimal efficiency in hydrogen fuel cells requires precise control and monitoring of the ...
The significance of gas analysis At its core, gas analysis is about understanding what’s in the air. ...
Secondary ion mass spectrometry (SIMS) is advantageous for its high sensitivity and the ability to provide high spatial resolution elemental and molecular information as a function of depth. This makes SIMS imaging an essential tool for depth profiling, where samples’ chemical/molecular information is investigated layer by layer. It is compatible with a wide range of different species, ...
What are Fuel Cells? Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a battery, and a dynamic equilibrium is maintained. ...
HOMER can model grid-connected and off-grid micropower systems serving electric and thermal loads, and comprising any combination of photovoltaic (PV) modules, wind turbines, small hydro, biomass power, reciprocating engine generators, microturbines, fuel cells, batteries, and hydrogen storage. The analysis and design of micropower systems can ...
A key criterion in microbial fuel cell (MFC) design is that the bio-electrochemical reaction between bacteria and the bulk solution should occur evenly on the electrode surface in order to improve electricity generation. ...
Fuel cell technology is one of the promising systems for cleaner and competitive alternate power generation systems. When the high temperature fuel cells like solid oxide fuel cell and molten carbon fuel cell are integrated with the gas turbines, the total ...
The characteristics of the Solid Oxide Fuel Cell (SOFC) were introduced. The SOFC system can be divided into ten sections based on the Second Law of Thermodynamics. The fuel specific consumption was taken as the primary indicator to investigate the specific consumption for each section. ...
This paper presents a comparative exergy study of the performance of various gas turbine power generation plants and a high temperature Solid Oxide Fuel Cell (SOFC). The overall system is analysed and its exergy efficiency and exergy destruction are obtained, as well as individual models of each component. ...
Interdigitated polymer electrolyte fuel cells are particularly attractive due to the enhanced transport rates and benefits with respect to electrode flooding. A 2D isothermal model is used to simulate the outlining processes that occur at the elemental fuel cell level. A Finite Element Method analysis is ...
This paper presents the thermodynamic modelling of a proton exchange membrane (PEM) fuel cell at various operating conditions through energy and exergy analyses. In addition, the correlations and equations available in literature were used to determine thermodynamic irreversibilities in the PEM fuel cell at different operating ...
Simulated performance of the plant with respect to variations in some design and operating parameters has been reported. While energy analysis indicates that such a plant would offer a large fuel saving, the exergy analysis identifies the components responsible for major exergy destructions. Higher pressure ratio across the GT is found to improve ...
In the present work, energy and exergy system analysis are used to estimate the thermodynamic performance of a SOFC system fuelled by methane. ...
Heat engines based on fossil fuel combustion produce harmful pollutant emissions. Environmental concerns and sustainable development call for new technology for energy conversion and power generation, which is more efficient, environmentally friendly and compatible with alternative fuels and renewable energy sources and carriers. Fuel cells meet all these requirements and are being rapidly ...
