One-dimensional Simulation Study of Intermediate Temperature Fuel Cell
(2024) MVKM05 20241Department of Energy Sciences
- Abstract
- In the past decade, there has been a major shift in automotive propulsion systems from fossil fuel vehicles to environmentally friendly, zero-emission transportation. This has made hydrogen-powered vehicles a hot topic. Volvo Group has launched a fuel cell truck to promote energy transition. A fuel cell consists of two electrodes (anode and cathode) and an electrolyte membrane inserted between them. A single fuel cell can produce a theoretical voltage of about 1.2 volts. Proton exchange membrane fuel cells (PEMFCs) are considered to be commercially promising fuel cells due to their high efficiency, low-temperature operation, high power density, fast start-up, and system robustness. However, in reality, the voltage output will drop due to... (More)

Proton exchange membrane fuel cells (PEMFCs) are considered to be commercially promising fuel cells due to their high efficiency, low-temperature operation, high power density, fast start-up, and system robustness. However, in reality, the voltage output will drop due to various polarization losses. In order to effectively utilize fuel cells, mathematical models must be established to predict the system behaviour under different conditions such as load current, reaction gas pressure, temperature, and stack voltage through computer simulation during the design stage.
Research shows that PEMFC faces some problems when operating below 80°C and above 120°C. Medium-temperature PEMFC can achieve a good balance. However, it is still unclear how changes in each parameter within the fuel cell will affect the output performance. This thesis combines previous research and attempts to explain the effects of different parameters on the polarization curve in the model. This work will provide direction for the calibration of more accurate fuel cell models. (Less) - Popular Abstract
- The research objective of this paper is fuel cells. Fuel cells are a power generation device that can convert the energy stored in hydrogen into electrical energy. Because the reaction of hydrogen and oxygen only produces water, fuel cells are ideal for clean energy. At the same time, because there is no movable structure in the components of fuel cells, they are easy to produce and have a long life. There is a great development prospect in the future.
Among many different types of fuel cells, proton exchange membrane fuel cells are the fuel cells with the most commercial potential. Because they are lighter than other designs and have lower operating temperatures and higher efficiency. They can also be started and stopped quickly when in...

Among many different types of fuel cells, proton exchange membrane fuel cells are the fuel cells with the most commercial potential. Because they are lighter than other designs and have lower operating temperatures and higher efficiency. They can also be started and stopped quickly when in use. They can be used to make fuel cell vehicles. It is currently found that proton exchange membrane fuel cells operating at temperatures of 80℃ to 120℃ have many advantages. Including fast reaction rate and low cooling system load.
To predict and analyze the working performance of this fuel cell, it is necessary to model and analyze it on a computer. The purpose of this study is to determine in which direction more detailed modelling needs to be developed in the future through simple model construction. At the end of this thesis, a model with an acceptable of accuracy was obtained under a relatively simple setting, and some suggestions for further modelling in the future were put forward. Including further analysis of the movement process of the reactants inside the fuel cell and quantitative research on certain specific parameters. (Less)
