Gold M_Grid™

for SOFC / SOEC lab tests reliability and actual cell performances

Gold M_Grid™ is delivered as raw material,

Gold grid 1 mesh gauze platinum SOFC PEM wet electrochemistry counter electrodes fuel cell wire fil platine pt or au toile tissu manufacturer fabricant supplier heraeus advent goodfellows AlfaAesar 1 Material: gold 99.99 %; mesh opening: 0.9 x 1.4 mm; M_Grid thickness: 0.08 mm; flat rolled for improved electrical contact; Fiaxell, as manufacturer and supplier delivers gold M_Grid™ in disc, rectangle or any shape on customer’s request

or customized on customer’s request

The gold M_Grid™, have been manufactured and supplied to replace the fragile standard gold mesh, gauze & fabric that can be purchased on the market. Gold M_Grid™ have been designed for SOFC / SOEC testing (in our SOFC test fixture for instance) but can also be used as counter electrode in wet electro-chemistry, PEM fuel cell, redox flow battery and corrosion applications or for the electro-plating and coating industry.

Customized gold M_Grid™ are manufactured for intensive use and every day new SOFC / SOEC cell mounting. Robustness is achieved with double layer gold grid welded together with flattened transversal gold wires. Contrary to commercial woven gold mesh, gauze & fabric that unravels and tears on the first test, gold M_Grid™ can be used hundreds of times.

Fiaxell is the manufacturer and supplier of the gold M_Grid™, showing higher mechanical and long term test performance than standard gold mesh, gauze & fabric available on the market place.

Why using gold M_Grid™ in SOFC / SOEC fuel cell research field ?

Gold (mesh, gauze, fabric & grid) does not interact with the SOFC / SOEC air electrodes and gives the actual cathode performances contrary to silver or platinum that act as a catalyst and artificially improve the results (see graph below by Steve Simner et. al.).

Platinum and gold mesh contacted to the cathode with Pt (or Au) paste (verified with 3+ tests). Steve Simner et. al (Page 16-19 of PNNL Cathode Development- SECA CTP Review 2005)

PtOx migration to SDC-LSF interface can be observed, platinum acts as a catalyst, contrary to gold which is inert and does not interact with the cathode material.
