Operator electric charge

Electrostatic Interactions. This is the mechanism that operates when adsorption sites and reagents carry opposite electrical charge signs. 

These do not pose a recognized static hazard if the curtain device and all equipment that could be electrically charged during operation is bonded and grounded [45,46].

Most fuel cells being developed consume either hydrogen or fuels that have been preprocessed into a suitable hydrogen-rich form. Some fuel cells can directly consume sufficiently reactive fuels such as methane, methanol, carbon monoxide, or ammonia, or can process such fuels internally. Different types of fuel cells are most appropriately characterized by the electrolyte that they use to transport the electric charge and by the temperature at which they operate. This classification is presented in Table 7.4.
