Abstract

A purpose of the present invention is to provide a curable resin composition which attains both low-temperature curability and a low compression set. Also provided is a sealing material for fuel cells, which is characterized by comprising components (A) to (D). Component (A): a vinyl polymer which has one or more alkenyl groups in the molecule and is liquid at 25oC Component (B): a compound havingone or more hydrosilyl groups in the molecule Component (C): a hydrosilylation catalyst Component (D): a heavy-metal deactivator comprising one or more compounds selected from the group consisting ofaminated triazine compounds, aminotriazole compounds, and hydrazide compounds

Description

technical field [0001] The present invention relates to a curable resin composition having both low-temperature curability and low compression set and excellent storage stability. Background technique [0002] In recent years, fuel cells have attracted much attention as a new energy system for automobiles and households. A fuel cell is a power generation device that generates electricity by chemically reacting hydrogen and oxygen. In addition, the fuel cell is a clean next-generation power generation device because of its high energy efficiency during power generation and the generation of water through the reaction of hydrogen and oxygen. Fuel cells include solid polymer fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, and solid oxide fuel cells. Among them, solid polymer fuel cells operate at a relatively low temperature (80 °C) and high power generation efficiency, it is expected to be used in power sources for automobiles, power generators for house...
