My 'case' for this is also exemplified by this link:

IT IS WRITTEN ANODE....! Told ya, it is not da same as eletrolysis which means yeah it would become negatively charged as electrons r lost by da H2 nd so flow from it to da other electrode. HOWEVER, it is da anode, da HYDROGEN FUEL CELL is different.....!
