Characteristics of Dynamic Load Response of a Fuel Cell with a Dead-ended Anode罗凡1,陈奔2,YANG Tianqi2,CAI Yonghua21. School of Information Engineering, Wuhan University of Technology2. School of Automotive Engineering,Wuhan University of Technology摘 要:The dynamic load characteristics of a proton exchange membrane fuel cell(PEMFC) with a dead-ended anode......
) The influence of dynamic load frequency on the two-sides is more obvious; (2) The dynamic load amplitude has the greatest influence on the stress concentration degree, and the plastic failure tends to develop to the deeper; (3) With the dynamic load source distance increase, the response of surrounding rock is gradually attenuated. On this basis, empirical equations for each dynamic load conditions were......
