Embodiment Construction

[0026] The present invention generally relates to the invention of fuel cell assemblies and methods of forming various fuel cell assemblies having longer life, lower cost and improved process efficiency. The present invention generally encompasses methods of treating or conditioning the surface of a substrate by depositing one or more layers of material having good substrate adhesion, low electrical resistance (high conductivity), and resistance to chemical attack during fuel cell operation. Better resistance. For example, the substrate can be a fuel cell component, a conductive plate, a separator plate, a bipolar plate, a unipolar plate, or an end plate, among others. But the invention is equally applicable to other kinds of substrates. The substrates of the present invention can be of any shape (eg, circular, square, rectangular, polygonal, etc.) and size. The type of substrate is not limited, and may be any substrate comprising metal, plastic, semiconductor, glass, carbon...

Abstract

The present invention generally relates to the creation of fuel cell components and the method of forming the various fuel cell components that have an improved lifetime, lower production cost and improved process performance. The invention generally includes treating or conditioning a substrate surface by depositing a material layer, or layers, having good adhesion to the substrate, low electrical resistivity (high conductivity) and has good resistance to chemical attack during the operation of fuel cell. The substrate may be, for example, a fuel cell part, a conductive plate, a separator plate, a bipolar plate or an end plate, among others. In one embodiment, the substrate surface is treated or conditioned by exposing at least a portion of it to a gas or liquid comprising ruthenium tetroxide.

Description

technical field [0001] Embodiments of the invention generally relate to the deposition of thin films. More particularly, the present invention relates to a process and apparatus for depositing a thin film on a substrate surface. Background technique [0002] Recently, various industries related to power supply and power production have paid considerable attention to the development of environmentally friendly energy. Various types of fuel cells can be used to directly generate electricity for applications such as portable electronic devices, cell phones, wireless devices, PDAs, cameras, portable stereos, notebook computers, motor vehicles (such as cars, trucks, trains, etc.), stationary large-scale energy equipment, residential electricity, etc. Because semiconductor processing technology can be easily applied to the manufacture of fuel cells, it is feasible to obtain high-efficiency electricity generation through fuel cells. [0003] A fuel cell is an electrochemical dev...
