Suvi Karvonen has suggested that using the modelling approach can help in understanding the functions of polymer electrolyte membrane (PEM) fuel cells. Karvonen’s recommendations will be presented and examined at the Aalto University.
Traditionally, research programmes on fuel cells has involved high costs and more time due to the fact that cells had to be manufactured and particularly tested for their functions. Modelling is an inexpensive and faster method and can provide variations.
According to Karvonen, the modelling approach provided information on the distribution of compression pressure in cells and its effect on the functioning of the cell. The tests established that the cells locally generate transverse electric currents, which may have a negative impact on the life of the cell. When the density in the cell is distributed unequally it causes uneven heating and as a result the cell core becomes dry. Eventually, the cell will start leaking oxygen and fuel and this will affect the working of the cell.
Simultaneously studies are being conducted to use fuel cells as electric car batteries. A fuel cell offers greater advantages over traditional batteries in terms of size and life time performance. However, the greatest challenge in using fuel cells is storing hydrogen, which is a difficult process. Suvi Karvonen’s research paper is titled, “Modelling approaches to mass transfer and compression effects in polymer electrolyte fuel cells”.
