Polymer electrolyte membrane fuel cells have attracted attention as energy conversion devices utilizing the use of pollution-free energy sources, oxygen (air) and hydrogen. In polymer electrolyte membrane fuel cells, water management is an important factor affecting performance. The lack of moisture in the polymer electrolyte membrane fuel cell causes problems such as a decrease in the conductivity of proton. Therefore, a humidification system is required to maintain sufficient proton conductivity for performance of fuel cell. In this study, an additional water supply channel is added to the separator plate of the fuel cell. Through this, it is possible to supply the moisture to the membrane and catalyst layer through the separator rather than the humidifying gas. |
