The performance of polymer electrolyte membrane fuel cell (PEMFC) greatly depends on the properties of the components. Bipolar plate is one of the key components of PEMFC and the properties of the plates on fuel cell performance are critical. Electrical conductivity and surface roughness of the bipolar plate appear very important properties to minimize ohmic resistance and optimize water management,...
Borohydride has been considered as a potential fuel for the fuel cell application due to its high energy density. A DBFC (direct borohydride fuel cell) is an electrochemical device that converts chemical energy stored in borohydride and oxidant directly to electrical energy as long as the fuel and oxidant is supplied. One of the main problems encountered in a DBFC is the simultaneous hydrolysis of...
The aim of this work is to determine the optimum operating conditions for the process of preparing anode electrocatalysts for direct sodium borohydride fuel cell (DSBHFC). Pt–Au/C electrocatalysts were studied as the anode catalysts while Pt/C were chosen as a cathode catalyst. Anode electrocatalysts were produced by the precipitation method. In this work, pH, temperature, drying time and Pt/Au ratio...
The water management is critical to achieve the full potential of PEMFC (polymer electrolyte membrane fuel cells). The surface contact angle and roughness properties of bipolar plate are the main factors affecting water management in a fuel cell and PEMFC performance. The effects of the contact angle and roughness of polymer composite bipolar plate and hydrogen flow rate on power density of PEMFC...
