...Levee Callahan; Jenn-Terng Gau; Siguang Xu; Minte Xiang To lower the cost of fuel cell bipolar plate (BPP), less expensive ferritic stainless steel (FSS) BPP substrate materials are investigated. A series of tensile tests and multistage microchannel-forming tests were conducted on 85-µm-thick...

... was investigated. The results of the feasibility experiments conducted to develop fuel cells with AA5052 bipolar plates having multiple microchannels were presented. The formability of microchannels under various types of pulsating loads was estimated for different punch loads and die radii using 0.3 mm thick...

... and the feature dimensions of the microchannel are in the same magnitude as the feature sizes of the material and tools reduced to micro/mesoscale. In this paper, an analytical model with consideration of the inhomogeneous stress/strain distribution was developed to predict the channel profile at different...
