V Congreso Nacional De Pilas De Combustible Water Transport Study in High Temperature Fuel Cell Stack
This work presents analysis of water transport phenomena in the 120 Wel high temperature PEM fuel cell stack. Phosphoric acid doped PBI membranes are known for their abilities to work with dry gases; however water in the electrolyte still plays an integral role in the proton conduction mechanism. The presence of water in the membrane increases proton conductivity, however at high operating temp...
متن کاملAsociación Española de XVIII CONGRESO NACIONAL Ingeniería Mecánica DE INGENIERÍA MECÁNICA Dynamics simulation of operation for a clutched arm
LARM clutched arm is a novel robotic structure with only one motor, where a proper clutched system provides 1-DOF dexterous mobility in 3D space. In this paper, modelling for the proposed mechanical design has been completed in ADAMS environment, with details like mass properties and friction coefficients. In particular, clutched system in the shoulder has been modelled suitably as key part of ...
