How do I get a serialized field saved into a PlayerPref?

When my player dies and then respawns his UI status indicator(health bar and text) has been removed from the array. I just learned about playerprefs so I might need to put my status indicator in there.

The code below is on my player... using UnityEngine; using System.Collections;

public class Player: MonoBehaviour {

 [System.Serializable]
 public class PlayerStats{
     public int maxHealth = 100;

     private int _curHealth;
     public int curHealth
     {
         get { return _curHealth; }
         set { _curHealth = Mathf.Clamp(value, 0, maxHealth); }
     }

     public void Init()
     {
         curHealth = maxHealth;
     }
 }

 public PlayerStats stats = new PlayerStats();

 public int fallBoundary = -20;

 public string deathSoundName = "DeathVoice";
 public string damageSoundName = "Grunt";

 private AudioManager audioManager;

 [SerializeField]
 private StatusIndicatorPlayer statusIndictorPlayer;
 
 void Start()
 {
     stats.Init();
     stats.curHealth = PlayerPrefs.GetInt("PlayerCurHealth");
     stats.maxHealth = PlayerPrefs.GetInt("PlayerMaxHealth");
     if (statusIndictorPlayer == null)
     {
         Debug.LogError("no staus indicator referenced on player");
     }
     else
     {
         statusIndictorPlayer.SetHealth(stats.curHealth, stats.maxHealth);
     }

     audioManager = AudioManager.instance;
     if (audioManager == null)
     {
         Debug.LogError("oh no, no audioManager in scene");
     }
 }

 void Update(){
     if (transform.position.y <= -20) {
         DamagePlayer (999999);
     }
 }

 public void DamagePlayer (int damage){
     stats.curHealth -= damage;

     if (stats.curHealth <= 0)
     {
         audioManager.PlaySound(deathSoundName);
         GameMaster.KillPlayer (this);
     }
     else
     {
         audioManager.PlaySound(damageSoundName);
     }

     statusIndictorPlayer.SetHealth(stats.curHealth, stats.maxHealth);
 }

}

I would really appreciate it if you could help me, it's quite a serious bug, thanks.
