A coating that performs on a flat coupon still needs to be assessed against your component design and operating environment. Sydrogen’s coating evaluation service helps engineering teams define the sample programme, compare coating options and identify the evidence needed for the next qualification stage.

For PEM fuel cell plates, the available scope includes contact resistance, corrosion behaviour, metallic-ion release, coating integrity and adhesion, water contact angle, accelerated stress and selected in-situ evaluation. For PEM electrolyser bipolar plates and porous transport layers, evaluation can connect initial and post-exposure resistance with electrochemical response, platinum loading and component compatibility. The test matrix and acceptance criteria are agreed for the application.

Custom SydroCOAT™ evaluation can also be discussed for materials, geometries or exposure conditions beyond the standard portfolio. These services support development and customer qualification; they do not constitute accredited third-party certification. Share your component, current coating, operating conditions and target limits to agree representative samples and an evaluation plan that informs your next design or supply decision.
