An electrode for a flow battery and a method for producing the electrode enable the electrode to be placed in contact with an electrolytic solution of the flow battery. The electrode includes a first portion consisting of particles of electrically conductive material having nanometric dimensions. The first portion is mesoporous with a porosity that increases the quantity of redox reactions per time unit in a flow of the electrolytic solution of the battery.

Electrode for a flow battery and production method

A PEM fuel or electrolysis cell with an extended lifetime, improved performance and uniform and stable operation is disclosed wherein a membrane electrode assembly is provided with a gradient of one or more properties in combination with a modification of one or more control parameters of the cell during its operation.

The flow battery comprises a first semi-cell (), wherein a first electrolyte is fed through a first electrode (); a second semi-cell (), wherein a second electrolyte is fed through a second electrode (); a partition membrane () disposed between the first electrode () and second electrode () in order to prevent them from reciprocally contacting with each other, and suitable to enable ions to permeate; and at least one porous barrier material layer () disposed between the first electrode () and second electrode (), and suitable to block an undesired flow of ions of one or both the electrolytes through the partition membrane (), the barrier material layer () having zones with different selectivities towards the ions whose flow is undesired.
