▎ 摘　　要

NOVELTY - A composition comprises vinyl ester resin system, a curing package, an additive package, and more than 0 to 0.2 wt.% graphene nanoplatelets. USE - Bulk molding compound (BMC) composition used for forming components of an electrochemical cell such as hydrogen cell and chemical storage battery (all claimed). ADVANTAGE - The bulk molded compounds (BMC) are mechanically stable, oxidation-resistant and corrosion-resistant, have a low shrinkage from mold, and have an improved compression molding performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) component, which is formed using the bulk molding compound composition; and (2) bipolar plate for use in an electrochemical cell, which comprises electroconductive plate molded from a vinyl ester-based bulk molding compound (BMC) thermostat composition having embedded graphene nanoplatelets. The electroconductivity of bipolar plate is 96-110 S/cm.
