Smoltek patent No. 83 now granted – the first in a new family

Elec­tro Cat­a­lyst Heat­ing is a new patent fam­i­ly in our IP port­fo­lio, and it describes nov­el designs for heat man­age­ment in elec­trol­y­sis cells. It uses the prop­er­ties of the cell to feed elec­tro­mag­net­ic ener­gy which is con­vert­ed to heat at the cat­a­lyst layer.

ith this new patent fam­i­ly, we are strength­en­ing the scope our IP port­fo­lio with­in the field of green hydro­gen pro­duc­tion using PEM elec­trolyz­ers. The inven­tion allows to sus­tain larg­er tem­per­a­ture gra­di­ents in a cell such that parts which oth­er­wise eas­i­ly cor­rode like bipo­lar plates can oper­ate at more benign tem­per­a­tures. Basi­cal­ly the heat is con­cen­trat­ed to the cat­a­lyst lay­er, where it is of use.

Inno­va­tion descrip­tion of the Elec­tro Cat­a­lyst Heat­ing patent fam­i­ly
The Inno­va­tion in brief: An elec­trolyz­er com­pris­ing a heat­ing appa­ra­tus oper­at­ed by prop­a­gat­ing elec­tro­mag­net­ic fields.  
 
From the pub­lished abstract: An elec­trolyz­er com­pris­ing a first and a sec­ond elec­trode and an ion exchange mem­brane arranged in-between the first and the sec­ond elec­trode, where each elec­trode com­pris­es a con­duc­tive ele­ment. At least one of the elec­trodes com­pris­es a cat­a­lyst struc­ture, the cat­a­lyst struc­ture com­pris­ing an elec­tri­cal­ly con­duc­tive mate­r­i­al.
The elec­trolyz­er also com­pris­es at least one feed­ing means, where­in the feed­ing means is arranged to intro­duce a viable elec­tro­mag­net­ic field. The vari­able elec­tro­mag­net­ic field is arranged into the elec­trolyz­er with the pur­pose to cre­ate a tem­per­a­ture gra­di­ent in the elec­trolyz­er by increas­ing a tem­per­a­ture of the cat­a­lyst structure.
