Abstract
An electrochemical hydrogen compression apparatus and a method for the collection and compression of hydrogen. The apparatus includes a cathode having a surface that is modified with a Tafel inhibitor that inhibits the Tafel reaction at the cathode surface. The same cathode surface may also include a Volmer catalyst to enhance the Volmer reaction at the cathode surface. The apparatus and method can advantageously increase the pressure of collected hydrogen, and may be useful for supplying the hydrogen to energy producing devices, such as a fuel cell.
