The deflection of the endplate under clamping force has a vital effect on fuel cell performance. An optimal cross-sectional shape with high moment inertia is significant to maximize bending stiffness stack. Five shapes (rectangular, round, parabolic, rectangular + and parabolic) typical endplates are proposed. analytical study moments introduced analyzed. maximum cross-sections obtained display...

Microchannels typically have rectangular cross-sections, whereas biological channels, such as blood vessels and airways, circular cross-sections. The difference in cross-sections causes different fluidic behaviors, resulting differences between behavior microchannels channels. To simulate vitro, cross-sectional are required. We developed a microchannel with smooth channel wall, free from cracks...

The bremsstrahlung of accelerated electrons passing through a converter is used to study multiparticle photonuclear reactions. results calculations, numerical modeling, design, and testing special magnetic cleaning system obtain “pure” beam quanta when studying the cross-sections such reactions at LUE-40 linac are presented. based on commercially available permanent magnets rectangular cross-se...
