  • Non-isolated high step-up interleaved boost converter

    The output voltage available from renewable sources like photovoltaic panels, fuel cells and battery banks are too low to be practically utilised. Therefore, the available voltage must be stepped up considerably before connecting to the load. In this paper, a novel topology, which consists of two interleaved stages and five voltage multiplier cells, is presented. The topology is derived from a ...

  • 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 ...

  • Computational fluid dynamics analysis in microbial fuel cells with different anode configurations

    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. However, experimental optimization of MFC design over a wide range of conditions is limited. Computational fluid dynamics (CFD) technology makes it possible to evaluate ...

  • How Many Cells do I Need in my Fuel Cell? (Simple Fuel Cell Design Guide)

    As with Electrolyzers on my previous post, there are many nuances in the optimal design of a Fuel Cell.  The proper selection depends on the application, type of fuel cell, component selection and design (MEAs, flow fields, etc.) and a host of other factors.   However, I will start with a simple tool that will help determine some ...

  • Exergy analysis of gas turbine – solid oxide fuel cell–based combined cycle power plant

    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 thermal efficiency of the combined cycle can be obtained greater than 60%. In the present work, thermodynamic analysis of SOFC–GT combined ...

  • Energy and exergy analyses of an integrated fuel cell and absorption cooling system

    In this study, we carry out detailed energy and exergy analyses of a PEM fuel cell integrated with triple effect ammonia-water absorption cooling system and investigate the effect of different operating parameters such as pressure, temperature, membrane thickness and current density of the fuel cell on the outputs of the fuel cell, and COP of the cooling system. The results show that fuel cell ...

  • 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 ...

  • Hardware-in-the-Loop testing platform for distributed generation systems

    The rapid validation of the expected performance of distributed generation installations is a critical step in the design process. However, the plethora of distributed generator types and the uniqueness of the load characteristics make the testing quite challenging. This paper introduces an original approach to Hardware-in-the-Loop simulation aimed to evaluate the performance and suitability of ...
