Proton exchange membrane fuel cell (PEMFC)’s power conditioning system (PCS) for residential application always contains two stage converter configuration of the dc-dc converter and the power grid connection dc-ac inverter. As known well, the inverter tends to draw an ac ripple current at twice the output frequency. For fuel cell system, the ripple current has worse effect than the other system, since it reduces the fuel cell system’s output capacity and wastes the fuel. Worst of all, it shortens the fuel cell’s life span. In this paper, first, the power grid connection PEMFC PCS’s ripple current source and propagation are analyzed. Then, a ripple suppressing PCS topology configuration and controller are proposed to achieve the low input ripple current control.

Heating Technology

In order to realize the low temperature and rapid cold start-up of a proton exchange membrane fuel cell stack, a dynamic model containing 40 single proton exchange membrane fuel cells is established to estimate the melting time of the proton exchange membrane fuel cell stack as well as to analyze the melting process of the ice by using the obtained liquid–solid boundary. The methods of proton exchange membrane electric heating and electrothermal film heating are utilized to achieve cold start-up of the proton exchange membrane fuel cell (PEMFC). The fluid simulation software fluent is used to simulate and analyze the process of melting ice. The solidification and melting model and multi-phase flow model are introduced. The pressure-implicit with splitting of operators algorithm is also adopted. The results show that both the proton exchange membrane electric heating technology and the electrothermal film heating method can achieve rapid cold start-up. The interior ice of the proton exchange membrane fuel cell stack melts first, while the first and 40th pieces melt afterwards. The ice melting time of the proton exchange membrane fuel cell stack is 32.5 s and 36.5 s with the two methods, respectively. In the end, the effect of different electrothermal film structures on cold start-up performance is studied, and three types of pore diameter electrothermal films are established. It is found that the electrothermal film with small holes melts completely first, and the electrothermal film with large holes melts completely last.
