High purity hydrogen produced by hydrolysis of sodium borohydride can be used directly in (proton exchange membrane) PEM fuel cells for portable devices and automotive applications. The advantages of high storage capacity, quickly start, controllable reaction and mild condition, hydrogen...

Commercial sized (16 x 16 cm2 active surface area) proton exchange membrane (PEM) fuel cells with serpentine flow chambers are fabricated. The GORE-TEX® PRIMEA 5621 was used with a 35-[mu]m-thick PEM with an anode catalyst layer with 0.45 mg cm-2 Pt and cathode catalyst layer with...

This study, based on the Taiwan dynamic computable general equilibrium model—energy, hydrogen (TAIGEM—EH), provides an economic baseline forecast for petroleum and hydrogen economies in Taiwan in 2004–2030. Through survey data on existing energy sectors and other industries, TAIGEM—EH...

The transient phenomenon of fuel cell with 5cm2 active area is investigated in this study by current density step increase and switching voltage under different conditions. It is found that there is an undershoot when the current density step increase is at the loading of 60% RH anode cathode, 3...

The operating temperature and internal water accumulation influence the fuel cell performance significantly, and various regions inside the fuel cell still have non-uniformity. At present, only external, invasive, theoretical and simulation methods are available. The real information inside the...

Commercially available tapes (anode, electrolyte) and paste (cathode) were choosen to prepare anode-supported cells for solid oxide fuel cell applications. For both anode-supported cells or electrolyte-supported cells, the anode needs pretreatment to reduce NiO/YSZ to Ni/YSZ to increase its...
