A 4-cell miniature direct formic acid fuel cell stack with independent fuel reservoir: Design and performance investigation

Proton Exchange Membrane Fuel Cell (PEMFC) is very good at producing energy without the emission of any harmful gases. In this work, emphasis has been given towards controlling the water accumulation inside the cell stack. The effective cooling of the fuel cell during operation can significantly improve the efficiency. Also, flooding and dehydration conditions are most common reasons for the efficiency reduction and performance degradation of the fuel cells. In the current work, the problem is addressed by controlling the number of cells in operation through a specifically designed microcontroller. The controller would switch the cells on/off when the need arises which can be diagnosed by thermocouple by virtue of cell temperature. Automatic switching with the microcontroller is performed without disturbing the stack operation. This could improve the cell performance with reduced flooding/dehydration of the stack. So the same stack life may be improved substantially.

This paper presents a novel architecture for a proton-exchange membrane (PEM) fuel cell stack, which is based on the concept that every cell in the stack works at the same condition and thus each cell has the same contribution to the overall output voltage and power. To meet this proposed requirement, special flow distributors were used to evenly distribute fuel and airflow to every fuel cell in the stack. Details of the flow distributor and experimental tests of a four-cell fuel cell stack are presented in the paper. The experimental results demonstrated the desired high performance of the fuel cell stack. It is proved that the novel architecture for fuel cell stack is successful and of significance to the development of high performance fuel cell stacks.
