摘要:
In an electrode in electrochemical device, particularly an anode lithium ion secondary battery, a cathode for use in alkali storage battery, an electrode for use in fuel cell, or a capacitor electrode, a metal structure has nano size micro-pillars is constructed with an electrode active material being formed on the surface of the metal structure. The metal structure having nano size micro-pillars can be formed, for example, by forming a metal layer as an electrode material by plating to the surface of a substrate having pores and then removing the substrate by dissolution, the metal filled in the pores of the substrate to form a group of micro-pillars. And the active material can be formed by depositing metal by plating. Since the active material is in direct contact with the conductive skeleton, the conducting agent for connecting the active materials to each other may not be added at all.

摘要:
An electrocatalyst for use in a fuel cell includes a carbon material as base support. An intermediate support with surface asperities is provided at least on a portion of the surface of the carbon material. Pt or a Pt-containing alloy particles supported on the intermediate or on the intermediate and the carbon material.

In An electrocatalyst for an electrode in a fuel cell, it comprises a support, a catalytic metal particle supported on the support, an intermediate made of a metal different from plutinu formed on the support, and a solid polymer electrolyte layer formed on the support. The catalytic metal particle is formed on an exposed surface of the intermediate.

An the electrode for electrolysis of an electrolytic solution comprises an electrode core serving as a base and a plurality of prominences formed on a surface of the electrode core, the prominences have each a leaf-shaped form and rises from the electrode core surface.
摘要:
An engine system comprises a detection means for detecting a supply quantity or supply pressure of hydrogen rich gas which is disposed in a hydrogen rich gas supply pipe for supplying hydrogen rich gas to a combustion chamber of the engine, a hydrogen rich gas supply valve control means for controlling the supply of hydrogen rich gas by controlling the open/close timing and the amount of open/close lift of the hydrogen rich gas supply valve disposed in the combustion chamber of the engine based on the supply quantity or supply pressure detected by the detection means, an inlet valve for supplying air to the combustion chamber of the engine separately from the hydrogen rich gas supply valve, and an inlet valve control means for controlling the volume of air taken into the combustion chamber of the engine by the inlet valve.
