“…Micromachined silicon has also been used as GDM for microPEM fuel cell applications tested with hydrogen/air [49]. The technique of incorporating sintered stainless steel fibre felt was implemented by Yi et al [50] and they inferred that the compressive modulus and ductility of GDL were improved. In addition, they claimed that the characteristics of treated stainless steel fibre felt were comparable to carbon paper.…”

“…From the various studies in open literature [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57], it is observed that though carbon cloth and carbon paper have their own pros and cons, carbon paper has been recommended by most of the authors especially for low humidity operation and carbon cloth for high humidity operation. The worst performance of the carbon cloth is likely to be attributed to contact resistances; however, at high current density, carbon papers have some issues pertaining to water management.…”

The operation of polymer electrolyte membrane (PEM)-based fuel cells involves numerous physicochemical processes and components actively governing its function and, among them, gas transport phenomena and gas diffusion layer (GDL) are noteworthy, and the present paper provides a comprehensive assessment on gas diffusion mechanism, geometry of GDL components and related modelling studies involved in GDL fabrication. The impact of GDL on diffusion of reactants, water management and the transport of ions has also been systematically dealt.

“…More methanol will react at the right place, the anode catalytic layer, increasing the bubbles number and improving the gas distribution over the active area. Additionally, the authors also believe that the SSM placed at the cathode side can eventually help on the removal of water droplets, as suggested by Yi et al [22]. Given the better performances obtained when using SSMs, combinations of meshes used simultaneously at the anode and cathode sides were also explored.…”

Abstract:In this study, the cascading metal foams were used as catalyst supports for constructing a new type of cylindrical laminated methanol steam reforming microreactor for hydrogen production. The two-layer impregnation method was used to load the Cu/Zn/Al/Zr catalysts, and the ultrasonic vibration method was then employed to investigate the loading performance of metal foams with different types and thicknesses. Furthermore, the effect of the type of catalyst placement, pores per inch (PPI) and foam type on the performance of methanol steam reforming microreactor was studied by varying the gas hourly space velocity (GHSV) and reaction temperature. Compared with two other types of catalyst placement studied, the microreactor containing catalyst-loaded metal foams without clearance cascading (3×2) showed the highest hydrogen production performance. When the PPI of the metal foam was increased from 50 to 100, both the methanol conversion and the H2 flow rate gradually increased. Our results also showed that a microreactor with Cu foam as a catalyst support exhibits increased hydrogen production and higher stability than those of a microreactor with Ni foam.
