Application
Energy and electrochemical hardware.
Screening material compositions and coating variants where conductivity, corrosion resistance, catalytic activity, stability, and surface change have to be balanced.
Physical screen
Electrochemical hardware choices start with local measurements on wafer libraries.
Electrochemical wafer library
The gradient is carried by the circular wafer, with selected positions measured for activity, stability, or corrosion response.
Scanning droplet cell
Local electrochemical measurements happen at defined wafer positions before hardware validation.
Electrochemical sample blanks
Selected coating directions can move into mesh, plate, coupon, disk, or strip samples for later hardware testing.Decision problem
Electrochemical hardware often fails through property tradeoffs.
Catalyst, bipolar-plate, current-collector, and conductive protective coating questions often require several properties to move together. xemX can use screening to compare composition and process windows before cell, stack, component, or supplier validation starts.
Customers can bring an electrocatalyst, current collector, bipolar plate, conductive coating, or corrosion-stability question where a measured composition window, process window, or coated sample set is needed before larger electrochemical tests.
Screening campaign
Create related catalyst or coating variants and compare activity, stability, conductivity, corrosion response, and surface change.
Prototype coating project
Start from a narrower coating, current-collector, bipolar-plate, mesh, PTL, GDE, carbon, or supplier question when the substrate and route fit.
What can be measured
Composition, phase, localized electrochemical response, activity indicators, stability indicators, corrosion response, sheet resistance, and surface change.
What comes back
Composition-activity maps, corrosion/stability tradeoff maps, coating compositions to repeat or avoid, and follow-up coated samples for the next electrode or cell-level test.
xemX can prepare follow-up electrochemical coatings or sample structures when technically scoped. Final cell, stack, product analysis, lifetime testing, and field validation usually remain downstream.
