Articles of manufacture possessing corrosion resistance characteristics are described, in particular for use in the chlor-alkali and other industries. The articles are formed from a resin composition, e.g., a cyclic olefin composition, polymerized with a Group 8 olefin metathesis catalyst. In particular aspects, an electrolytic cell component, such as a cell cover for use in the electrolysis of brine, may be formed from the resin composition. Among other benefits, such articles provide improved corrosion resistance compared to articles molded from other resin compositions, such as fiberglass reinforced polyesters and vinyl esters, and two-component dicyclopentadiene (DCPD) resins comprising molybdenum or tungsten pre-catalysts.

A system for controlling an electrochemical production process includes a variable controllable power circuit and an electrolytic cell. The cell includes two electrodes and operates in different states dependent on the potential difference across the electrodes. The system includes a power circuit controller that causes the power circuit to apply a given potential difference across the electrodes to initiate operation of the cell in the one of multiple possible states associated with the given potential difference. The possible states include a production state associated with a first non-zero potential difference in which a product of interest is produced, and an idle state associated with a second non-zero potential difference in which the product of interest is not produced. A monitoring and control subsystem maintains a predefined set of production process conditions, including a predefined operating temperature range, while the cell operates in both the production state and the idle state.
