摘要:
A hydrogen storage system is described that can fabricated under ambient atmospheric conditions and humidity. The hydrogen storage system includes hydrogen-absorbing alloy particles, such as ABx-type alloys, for example LaNi4.7Al0.3, AB/A2B-type alloys, for example Mg2Ni, and AB2-type alloys, and group VIII transition metal particles, such as Pd, Pt, Ni, Ru, and/or Re, that are mechanically alloyed. The mechanically alloyed particles are stable and retain their hydrogen-absorbing efficiency even after prolonged exposure to air and water. Binders and solvent can be added to produce low-viscosity inks. The hydrogen storage system can be used with fuel cells that can be microfabricated and optionally be integrated with electronic devices.

摘要:
A fuel cell system having flow fields capable to operate like interdigitated flow fields, but in the same time allowing the removal of liquid water collected in the high-pressure channels, throughout individual exhaust passages. In a preferred embodiment, the channels follow radial-circumferential trajectories, each channel being provided with individual exhaust passages. In another preferred embodiment, each channel is provided with a valve control in both individual supply passages and individual exhaust passages allowing the system to operate alternatively as an interdigitated flow field as well as an open-channel flow field.
