Abstract: A solid oxide fuel cell (SOFC) includes a cathode having a yttria stabilized zirconia (YSZ) structure. The YSZ structure is in contact with a solid electrolyte layer. A lanthanum strontium manganite (LSM) structure is deposited on the YSZ structure to form a composite cathode. The cathode includes a catalyst layer. The catalyst layer is a mesoporous nanoionic catalyst material integrated with the YSZ and LSM structures. Alternatively, or in addition to, the mesoporous nanoionic catalyst material may be coated onto the YSZ and LSM structures or embedded into the YSZ and LSM structures. The mesoporous nanoionic catalyst material may form an interconnected fibrous network.

Abstract: A method of making a reversible hydrogen electrode comprises filling a housing with electrolyte, the housing having an open end, a closed end and a platinum wire having an internal portion in the housing and an external portion extending through the closed end to an exterior of the housing. The housing is inverted into a container of electrolyte and a counter electrode is placed into the container of electrolyte, the counter electrode being metal. A power source is attached to the external portion of the platinum wire and the counter electrode. The power source is run for a period of time to produce electrolysis. Hydrogen is formed at the internal portion of the platinum wire and oxygen is formed at the counter electrode. A single hydrogen bubble is formed in the housing, the platinum wire extending through the single hydrogen bubble.

Abstract: Cathodes for lithium-sulfur batteries inhibit the parasitic polysulfide shuttle effect. The cathodes contain an active material support having a transition metal-containing nitrogen doped carbon developed to host the sulfur and suppress the diffusion of polysulfides into the electrolyte by retaining them in the high surface area nanostructured pores of the carbon while the transition metals serve as anchors for the soluble species due to the transition metals' affinity for sulfur. The cathodes 12 are gram scalable and have high surface area and high conductivity. The cathode active material support includes a nitrogen-containing polymer structure doped with a sulfide precursor of one or more transition metals selected from the group containing Fe, V, Mo, W, Co, Ni, Cu and Zn.
