Electrochemical Researcher for H2 Sustainable Technologies

Context

The Isbergues Research Center is the laboratory dedicated to the study of stainless steels for the European manufacturing plants of the APERAM group. It employs approximately 70 people whose activity consists of defining, industrializing, and supporting the commercial development of new stainless steels. As such, it is APERAM’s reference Research Center for stainless steel metallurgy, in‑use properties, and flat product manufacturing processes.

The Solutions team is responsible for providing scientific expertise to the sales team to understand the technical requirements of various markets. The team of application engineers and technicians focuses on the usage properties of the various stainless steel grades offered by APERAM and the development of future market solutions. In addition to traditional stainless steel markets, mobility, energy, and recycling are addressed as high‑priority strategic programs for the company. Research programs involve internal resources and facilities but also require building strong relationships with our various partners (customers, end‑users, technical institutes, universities).

Missions

• EIS Modeling: Master Electrochemical Impedance Spectroscopy (EIS) to differentiate physical phenomena at interfaces (charge transfer resistance, double‑layer capacitance, etc.).
• Coating Characterization: Evaluate the integrity and porosity of protective coatings via EIS and voltammetry to guarantee optimal long‑term corrosion protection.
• New Energy Research: Develop specific testing protocols (accelerated aging tests) for alkaline electrolyzers and CCUS systems, where pH and pressure conditions drastically influence electrochemical thermodynamics.
• Corrosion Mechanisms: Identify failure modes (general, crevice, pitting corrosion, etc.) by coupling electrochemical measurements with advanced surface analyses such as SEM, XPS, or Raman spectroscopy.
• Materials Innovation: Propose improvements to steel grades and surface treatments to minimize Interfacial Contact Resistance (ICR) while maximizing chemical resistance.
• Watch and Academia: Lead theses and external collaborations to remain at the forefront of experimental methodologies in electrochemistry.
