Modeling and Parameters Identification of PEM Fuel Cell for Application to a Hybrid Vehicle System | Chapter 5 | Research Trends and Challenges in Physical Science Vol.8

 In this chapter, we are interested in the research of fuel cell instrumentation, particularly that of the proton exchange membrane type PEM, by measuring complex impedance in order to predict faults and avoid serious stack problems such as drowning or reversal phenomena. As a result, this paper examines the...

Studies on the Stiffness Properties of Pinus caribaea Round Timber Logs

The current study evaluated the estimate of the longitudinal (E) and transversal (G) elasticity modulus of the round structural beams of Pinus caribaea timber in order to verify whether the relationship between the two modules of the Brazilian Standard ANBT NBR 7190 is actually reliable for this species of...
