Removal apparatus e.g. for residual oxidant in fuel cell system, has pressure gauge to estimate pressure of absorbent tank and shut off valves positioned in inflow and outflow passages of fuel cell system and of tank, respectively

摘要

A vacuum pump (700) is connected to an adsorbent tank (500) for separating residue absorbed from a fuel cell system (200) by the adsorbent in the tank. A pressure gauge (800) estimates the pressure of the tank. Each shut off valve (100,300,400,600) is positioned in inflow and outflow passages of the flow fields in fuel cell and of the tank, respectively. An independent claim is also included for removing method of residual oxidant, gas fuel and water in fuel cell system.
