Definition - Primary Galvanic cells
• have a fixed quantity of stored reactants • operate in a closed enviroment
What are the common design features of primary galvanic cells?
• type of electrodes (inert/reactive) • type of electrolyte (acidic/basic/other) • type of salt-bridge
What are some factors that should be considered when designing primary galvanic cells?
• species in environment that may interfere with cell function • products/reactants/potential malfunctions that may be dangerous to humans • environmental impacts • ability to source materials • economic factors
Definition - Porous Seperator
• prevents oxidant & reductant from coming into contact with each other • allows ions to flow from one half-cell to another
