Evaluation of Pt/C catalyst degradation and H2O2 formation changes under simulated PEM fuel cell condition by a rotating ring-disk electrode

The energy saving mechanism of gas diffusion electrode based on Pt/C catalyst for saving energy and green electrodeposition of manganese dioxide

“…2B, respectively. The particles have an irregular shape in agreement with Pt particles shape of Ono et al [28]. The average particle size is about 3.8 nm and highly dispersed on the carbon (VXC72R).…”

Kinetic Study of Oxygen Reduction Reaction in Acid Solution Using Titanium Oxide-based Catalysts Prepared from Oxy-titanium Tetra-pyrazino-porphyrazine

“…The value of x H2O2 was sufficiently small and essentially similar to that of the platinum catalyst. 6 The creation of the active sites for the ORR appears to be related to the presence of rutile-type TiO 2 with low crystallinity.…”

Step by step development of a real fuel cell system. Design, implementation, control and monitoring

“…Additionally, an external power source will supply all the devices which are included into the BoP. The needed of this external electrical source is inherent to fuel cell system for two reasons: 1) BoP devices should be activated even before the fuel cell system starts running, and 2) the time required for fuel cell system to reach steady-state performance and deliver rated power is a function of the difference between the stack temperature and the optimal operating temperature [18], the hydration state of the membrane [19] and the condition of the catalyst [20].…”
