System Design and Components

In addition to the development of electrodes and electrode structures, there are many options for the system and stack setup. Some patents and papers focus on the basic principles of the system, whereas other patents describe advantageous designs in detail. 

2) An example of a more complex setup is a system that operates as a power booster. In this system, a conventional FC is supplied with hydrogen by a 

Systems with one oxidation and one reduction electrode were developed in the 1990s. The advantage of this technique is the more durable electrodes. The 

In addition to the stability of the catalysts and the electrodes of a URFC, the durability of the stack and system components has also been investigated. Titanium plates are the best candidates as bipolar material owing to their sturdiness in highly acidic and humid conditions with no corrosion at high positive overpotentials [84, 85].
