1.	Due to which of the following the separator is made porous?(a) To dissipate heat(b) Increases efficiency(c) Allow the diffusion of acid(d) Acts as a pressure reliefI had been asked this question by my college professor while I was bunking the class.My doubt is from Lead-Acid Battery in portion Storage Batteries of Automotive Engine Design
Answer» Right option is (c) Allow the diffusion of acid To elaborate: The material of the SEPARATOR, apart from being non CONDUCTING, must be sufficiently porous or PERFORATED to allow diffusion of the acid. The separator must be slightly thinner than space into which they fit.
