Development of a Bi-cell Proton Exchange Membrane Fuel Cell with Optimized Groove-designed Piezoelectric Actuator

H. K. Ma, W. F. Luo, Y. L. Hsu
Previous studies demonstrated a piezoelectric proton exchange membrane fuel cell (PZT-PEMFC) stack design composed of three bi-cells in series and a single bi-cell, with a maximum net power density of 0.1608 W cm−2. The present study developed a modified bi-cell design with lower volume and weight by using gold-plated aluminum 6061. A groove-designed PZT actuator enclosed with poly-di-methyl-siloxane (PDMS) curing for 30 min can reduce uneven air feeding. Such an actuator can also improve the performance of both sides of a bi-cell, with only a 0.7% difference in the open circuit voltage (OCV). The experimental results showed that the net power density of the new version of the single bi-cell PZT-PEMFC module was 0.1658 W cm−2.
