Experimental investigation is carried out on passive direct methanol fuel cell, to study with the selected combination of different anode and cathode current collectors which have high electrical and thermal conductivity together with corrosion resistance compatibility properties. These collectors are fabricated with an opening ratio of 45.3% on St...

Purpose The purpose of this paper is to investigate the performance of Passive Direct Methanol Fuel Cell (PDMFC) experimentally using various Membrane Electrode Assembly (MEA) shapes such as square, rectangle, rhombus, and circle with equal areas and equal perimeters. The variation in MEA shape/size is achieved by altering gasket openings in the dy...

Analysis of buoyancy effect on the evaluation of carbon dioxide gas from passive direct methanol fuel cell current collectors’ (CCs’) openings is carried out. Two types of setups are chosen for the analysis, one with taper cylindrical openings and the other with uniform cylindrical openings. The analysis shows that buoyancy is more effective in tap...

To attract and get a major share of the passive direct methanol fuel cell in the global market, optimization of the influencing parameters like system durability, effectiveness, productivity, availability, and competitive price are to be balanced for achieving the excellent performance of cell for electricity generation and charging portable electr...

The prime intention of this chapter is to introduce fuel cells for the sustainable energy needs of the future world. With increase in demand for electrical power globally, the need for developing a variety of renewable energy conservation is getting significant for sustainable development in the electrical power sector, keeping environmental protec...

The International Energy Agency estimated that 50% of the world's electricity is being consumed by only four main equipments, viz., motors, air conditioners, refrigerators, and lighting. This chapter discusses all of this electrical equipment with respect to energy‐saving components in each of them and the application of digital technology and Inte...

From the inception, Direct Methanol Fuel Cell (DMFC) is made suitable for various appliances which include stationary and portable electrical applications as it is considered as a notably highly promising one amongst energy sources in renewable energies. Its ion or proton conducting electrolyte is based totally on polymer electrolyte membrane (PEM)...

Take responsibility for your own safety when you weld, cut or grind. Wear the right PPE, maintain a safe workplace and follow the safety rules that apply to your job. This article describe new ideas on safety procedures.

ASME Boiler and Pressure vessel code (BPVC) Section VIII Division 1 is focused on a design-by-rule approach and Division 2 on design-by-analysis approach. While ASME Section VIII, Division 1's design-by-rule approach is most commonly utilized by engineers to size the pressure vessel according to the application requirements, it is quite a conservat...

The objective of maintenance and reliability in any industry having mechanical equipment is to maintain the capability of the system while controlling costs. Maintenance is all activities involved in keeping a system's equipment in working order by implementing or improving preventive maintenance and increasing repair capability whereas Reliability...

RMA-4 quality rubber is one of the best barrier protections between metal and acids. Rubber hardness is one of the most widely measured properties used to characterize rubber. IRHD (International Rubber Hardness Degree) scale and the Shore-A scale are two testing methods widely accepted. The two test methods use totally different indentor geometrie...
